It is reason to be suspicious if you want to be suspicious - but it does NOT show that something is actually happening.
Less lethal than what?
All het proposed versions of SRM by stratospheric injection of aerosols involve SOx, not any of ther others at all - why do you mention them?
2) for the conduct of a narrow class of research in emergency settings; and 3) for use by the Department of Defense (DoD) of specific investigational products in combat exigencies

A similar pattern is being evidenced here on ATS where those that thing geoengineering/adaptation is currently going on are called paranoid schizophrenic, paranoid, and other mental health insults.
There is plenty of anecdotal "whistleblower" data that it is happening.
That on top of the billions they are pouring into geoengineering/adaptation is plenty of reason to be suspicious given their track record of proceeding with operations years ahead of their admitting.
Less lethal than the Tuskegee Syphilis Experiments, MK ULTRA, and radiation experiments I referenced here.
All the others have been repeatedly mentioned throughout the geoengineering papers including some we have not mentioned such as H2So4. Re-watch "What In The World Are They Spraying" and you can hear geoengineers talk about some such as aluminum.
I find it fascinating that mat offers scientific paper after scientific paper and they are all ignored.
WASHINGTON D.C. - October 31, 2007 – Today in a hearing before the House Committee on Science and Technology, NASA Administrator Michael Griffin agreed to release data from a controversial airline safety study by the end of the year.
The National Aviation Operations Monitoring Service (NAOMS) study has recently been in the press due to an Associated Press (AP) Freedom of Information Act (FOIA) request.
Today, Griffin agreed to release the data, once it is appropriately “scrubbed” to protect the anonymity of the pilots who were surveyed. He also expressed his regret for the language NASA used in responding the FOIA request, saying, “I regret any impression that NASA was in any way trying to put commercial interests ahead of public safety. That was not and never will be the case.”
Griffin continued, “I have directed that all NAOMS data that does not contain confidential commercial information, or information that could compromise the anonymity of individual pilots, be released as soon as possible.”
Science and Technology Ranking Member Ralph Hall (R-TX) praised Administrator Griffin’s candor and commitment to transparency, saying, “I do want to associate myself with NASA Administrator Mike Griffin’s public statement that lays out the agency’s philosophy on the treatment of research data. Like him, I believe NASA ought to be in the business of putting information in front of the public, not withholding it.
“That being said,” Hall continued, “every care should be taken to protect the identities of survey respondents. NAOMS promised pilots complete confidentiality to ensure their candid participation, and that ought not be breached. If information is disclosed that may allow respondents to be identified, there will be a serious chilling effect in future survey efforts funded by the federal government, whether we’re talking about pilots or other citizen groups who provide our government meaningful insight into a whole host of activities. In the case of NAOMS, we should be cognizant of striking a balance between transparency and confidentiality.”
Echoing the need for stringent confidentiality in order to elicit candid survey responses from pilots, Captain Terry McVenes, Executive Air Safety Chairman for the Air Line Pilots Association, who represents some 60,000 air line pilots, said that, “Regardless of the solution, it is important to keep in mind that raw data, distributed without appropriate analysis and scrutiny to ensure its validity, can lead to unintended consequences… Just as importantly, if raw data are simply distributed to the general public without the quality controls I’ve mentioned, it would undermine the confidence that pilots and the airline community have that voluntarily and confidentially supplied safety data will remain secure.”
Also testifying at today’s hearing were: Mr. Jim Hall, Managing Partner, Hall and Associates LLC, and Former Chairman, National Transportation Safety Board (NTSB); Mr. Robert S. Dodd, Safety Consultant and President, Dodd & Associates LLC; and Dr. Jon A. Krosnick, Frederic O. Glover Professor in Humanities and Social Sciences, Stanford University
On October 22, 2007, The Washington Post published an Associated Press news article,
“NASA Sits on Air Safety Survey,”
1
concerning NASA’s denial of a Freedom of Information Act (FOIA) request for the data collected via the National Aviation Operations Monitoring Service (NAOMS). One of the reasons cited for the denial was that the “[r]elease of the requested data, which are sensitive and safety-related, could materially affect the public confidence in, and the commercial welfare of, the air carriers and general aviation companies whose pilots participated in the survey.” That statement and the implication that the Federal Government spent taxpayer dollars to gather safety
data that NASA was withholding to protect commercial interests prompted a congressional inquiry.
On October 31, 2007, the NASA Administrator appeared before the House Committee on Science and Technology, along with the NAOMS principal investigator; the NAOMS Project survey methodologist; and the Executive Air Safety Chairman of the Air Line Pilots Association, International (ALPA),
to answer questions concerning NAOMS and the survey data. Subsequently, the Office of Inspector General (OIG) initiated this review of NAOMS, with the overall objective of reviewing the management of NAOMS.
We focused on understanding the history and status of NAOMS, to include its objectives, funding, and plans for using the NAOMS survey data. See Enclosure 1 for details on our scope and methodology

MOFFETT FIELD, Calif. -- An unprecedented national survey of pilots by the U.S. government has found that safety problems like near collisions and runway interference occur far more frequently than previously recognized. But the government is withholding the information, fearful it would upset air travelers and hurt airline profits.
NASA gathered the information under an $8.5 million federal safety project, through telephone interviews with roughly 24,000 commercial and general aviation pilots over nearly four years. Since shutting down the project more than one year ago, the space agency has refused to divulge its survey data publicly.
After The Associated Press disclosed details Monday about the survey and efforts to keep its results secret, NASA's chief said he will reconsider how much of the survey findings can be made public.
"NASA should focus on how we can provide information to the public, not on how we can withhold it," NASA Administrator Michael Griffin said in a statement. He said the agency's research and data "should be widely available and subject to review and scrutiny."
The NAOMS project was conceived and designed in 1997 to provide broad,long-term measures on trends and to measure the effect of new technologies and policies on aviation safety. Following the 1996 formation of the White House Commission on Aviation Safety and Security, and the commission’s 1997 report to the President committing the government and industry to “establish[ing] a national goal to reduce the aviation fatal accident rate by a factor of five within ten years and conduct[ing] safety research to support that goal,” NASA worked with FAA and NTSB to set up the Aviation Safety Investment Strategy Team within NASA.
11
This team organized workshops, examined options, and recommended a strategy for improving aviation safety and security. One of its recommendations led to NASA’s Aviation System Monitoring and Modeling (ASMM) project, a program to identify existing accident precursors in the aviation system and to forecast and identify potential safety issues to guide the development of safety technology.
12
ASMM, within NASA’s Aviation Safety and Security Program, was to provide systemwide analytic tools for identifying and correcting the predisposing conditions of accidents and to provide methodologies, computational tools, and infrastructure to help experts make the best possible decisions. ASMM was expected to accomplish this by, among other things
NAOMS focused its development efforts primarily on air carrier pilots. After planning and development, a field trial, and eventual implementation of the air carrier pilot survey and a smaller survey of general aviation pilots, the project effectively ended when NASA transmitted a Web-based version of the air carrier pilot data collection system to ALPA in January 2007.
To describe the history and nature of the NAOMS project, we researched, reviewed, and analyzed related material posted on several NASA Web sites and provided to us directly by NASA and its contractor for NAOMS. We reviewed relevant documents on the House of Representatives’ Committee on Science and Technology Web site. We examined relevant documents produced by the Battelle Memorial Institute (Battelle), National Academies, and others as well as information produced for the National Research Council. In addition, we reviewed a number of relevant reports, articles, correspondence, and fact sheets on the NAOMS project and air safety. Many of the publicly available materials we reviewed are named in the bibliography at the end of this report.
The NAOMS survey was intended to provide a better understanding of the safety performance of the aviation system, and to allow for the computation of general trends over time, in order to supplement safety systems. A survey with a different goal—one that was investigative or intended to understand the causes of events—would seek information different from those asked for in the NAOMS questions. Depending on the customers’ intended use of the data, developers of a future survey might consider writing questions that asked about, for example, the causes of engine failures or details about air crews’ experience of engine shutdowns. Whereas questions such as the latter would be consonant with NAOMS’s goal of describing precursors to safety events, the former would be more investigative. Developing a detailed analysis plan in conjunction with the questionnaire would help ensure that the survey included questions relevant for specific analyses.
We provided NASA and the Department of Transportation with drafts of this report for their review and comment. NASA reiterated that NAOMS was a research and development project and provided technical comments, which we incorporated as appropriate. NASA also expressed concern about protecting NAOMS respondents’ confidentiality, a concern we share. However, we noted that other agencies have developed mechanisms for releasing sensitive data to appropriate researchers. The Department of Transportation had no comments. We also provided a draft of this report to Battelle (NASA’s contractor for NAOMS) and the survey methodologist for NAOMS for their review. Battelle provided no comments on the draft report. The survey methodologist reported that he found the draft report to be objective and detailed, and that he believed i will contribute to the public debate on NAOMS. He also provided technical clarifications, which we incorporated into the report as appropriate
Aviation System Monitoring and Modeling (ASMM) Project Team's "Morning Report" was honored at R&D 100 Awards Ceremony Oct 20, 2005 The Aviation System Monitoring and Modeling (ASMM) Project Team received a prestigious R&D 100 Award from the editors of R&D 100 Magazine for the development of the Morning Report of Atypical Flights tool. Morning Report was also the recipient of the previously unannounced Editors' Choice Award for "the innovation most likely to impact public safety." Morning Report analyzes massive amounts of operational data to identify patterns and events that could signify problems during flight. The technology was developed by researchers at Pacific Northwest Laboratory in a joint effort with researchers at NASA Ames Research Center, Battelle Memorial Institute, Flight Safety Consultants, and ProWorks Corp. The awards banquet was held on October 20, 2005 in Chicago, Illinois. Tom Chidester, ASMM project lead, and Irv Statler from the ASMM project office at NASA Ames attended. The Morning Report of Atypical Flights tool searches for the unexpected and reveals the unknowns. The tool automatically analyzes the flight data recorded by each aircraft in an airline's fleet during a selected period of time. Then it brings to the safety analyst's attention all of the flights that were deemed atypical in a multivariate statistical analysis with respect to the main body of comparable flight data. Morning Report has also received a NASA Space Act Award and a patent is pending.
The Intercontinental Chemical Transport Experiment (INTEX-NA) is a major NASA science campaign to understand the transport and transformation of gases and aerosols on transcontinental and intercontinental scales and their impact on air quality and climate. A particular focus in this study is to quantify and characterize the inflow and outflow of pollution over North America. INTEX will also provide important validation of satellite observations with ongoing satellite measurement programs, such as Terra, Aura, and Envisat. The experiment will be conducted over the continental United States during the summer of 2004 using a variety of science aircraft. Several coastal and continental sites across North America have been selected as bases of operation. The experiment will be supported by forecasts from meteorological and chemical models, surface and satellite observations, and ozone probe releases.
The INTEX-NA campaign will be greatly facilitated and enhanced by a number of concurrent national and international field campaigns. The National Oceanic and Atmospheric Administration (NOAA) is the principal U.S. partner for NASA and will field coordinated airborne and shipboard platforms. Plans are also underway for the United Kingdom, Germany, Canada, and France to conduct concurrent airborne campaigns to measure the transport of pollution from North America into the eastern Atlantic and to Europe. Synthesis of the combined observations from surface, airborne, and space platforms will maximize scientific results and should directly benefit scientific understanding of air quality and its relation to climate change.
INTEX is sponsored by the NASA Office of Earth Science Tropospheric Chemistry Program.
The Ames Earth Science Project Office is a small group of success-oriented individuals providing project management for NASA's Science Mission Directorate field research. We provide planning, implementation and post mission support for large, complex, multi-agency, national and international field campaigns. We have a long history of successful field campaigns, beginning in 1987 with both the Stratosphere-Troposphere Exchange Project (STEP) and the Airborne Antarctic Ozone Expedition (AAOE) experiments. Our primary customer has been NASA's Upper Atmosphere Research Program, but in recent years our customers have included the Atmospheric Chemistry and Modeling Analysis Program, the Tropospheric Chemistry Program, the Radiation Sciences Program, Atmospheric Dynamics and Remote Sensing, the Suborbital Science Program, and the EOS satellite validation program

The Mid-latitude Airborne Cirrus Properties Experiment (MACPEX) is an airborne field campaign to investigate cirrus cloud properties and the processes that affect their impact on radiation. Utilizing the NASA WB-57 based at Ellington Field, TX, the campaign will take place in the March / April 2011 timeframe. Science flights will focus on central North America vicinity with an emphasis over the DoE ARM SGP site in Oklahoma.
Some of the major science questions to be addressed by MACPEX will include:
• How prevalent are the smaller crystals in cirrus clouds, and how important are these for extinction, radiative forcing, and radiative heating?
• How are cirrus microphysical properties (particle size distribution, ice crystal habit, extinction, ice water content) related to the dynamical forcing driving cloud formation?
• How are cirrus microphysical properties related to aerosol loading and composition, including the abundance of heterogeneous ice nuclei?
• How do cirrus microphysical properties evolve through the lifecycles of the clouds, and what role do radiatively driven dynamical motions play?
In addition to the in situ measurements, flights will be coordinated with the NASA EOS / A-Train satellite observations for validation, as well as, evaluation of new remote-sensing retrievals for future Earth Science Decadal satellites. The detailed measurements aquired by MACPEX will also be used to improve cloud model parameterizations in Global Climate Models (GCMs).
The MACPEX mission is supported by the NASA Earth Science Research and Analysis Program under the Atmospheric Composition Focus Area. The aircraft and support provided by the NASA Airborne Science Program.
ATTREX Logo
Despite its low concentration, stratospheric water vapor has large impacts on the earth’s energy budget and climate. Recent studies suggest that even small changes in stratospheric humidity may have climate impacts that are significant compared to those of decadal increases in greenhouse gases. Future changes in stratospheric humidity and ozone concentration in response to changing climate are significant climate feedbacks.
While the tropospheric water vapor climate feedback is well represented in global models, predictions of future changes in stratospheric humidity are highly uncertain because of gaps in our understanding of physical processes occurring in the Tropical Tropopause Layer (TTL, ~13-18 km), the region of the atmosphere that controls the composition of the stratosphere. Uncertainties in the TTL chemical composition also limit our ability to predict future changes in stratospheric ozone.
Airborne Tropical Tropopause Experiment (ATTREX) will perform a series of measurement campaigns using the long-range NASA Global Hawk (GH) unmanned aircraft system (UAS) to directly address these problems.
The Genesis and Rapid Intensification Processes (GRIP) experiment was a NASA Earth science field experiment in 2010 that was conducted to better understand how tropical storms form and develop into major hurricanes. NASA used the DC-8 aircraft, the WB-57 aircraft, and the Global Hawk Unmanned Airborne System (UAS) configured with a suite of in situ and remote sensing instruments used to observe and characterize the lifecycle of hurricanes.
The GRIP deployment was 15 August – 30 September 2010 with bases in Ft. Lauderdale, FL for the DC-8, at Houston, TX for the WB-57, and at NASA Dryden Flight Research Facility, CA for the Global Hawk. This campaign capitalized on a number of ground networks, airborne science platforms (both manned and unmanned), and space-based assets. The field campaign was executed according to a prioritized set of scientific objectives. In two separate science solicitations, NASA selected a team of investigators to collect NASA satellite and aircraft field campaign data with the goal of conducting basic research on problems related to the formation and intensification of hurricanes.
The spaceborne and airborne observational capabilities of NASA put it in a unique position to assist the hurricane research community in addressing shortcomings in the current state of the science. The relatively recent launch of several new satellites, the prospect of using a high-altitude UAS for hurricane surveillance, and the emergence of new remote sensing technologies offered new research tools that needed to be explored and validated. Of great importance were new remote sensing instruments for wind and temperature that can lead to improved characterization of storm structure and environment.
The GRIP hurricane field campaign and research project were managed by Dr. Ramesh Kakar, Weather Focus Area Leader within the Earth Science Division, NASA Headquarters in Washington, D.C. Dr. Kakar was primarily responsible for assembling the science team and the instrument payload for the NASA aircraft participating in this field experiment.
Hygroscopy is the ability of a substance to attract and hold water molecules from the surrounding environment through either absorption or adsorption with the adsorbing or absorbing material becoming physically 'changed,' somewhat: by an increase in volume, stickiness, or other physical characteristic of the material as water molecules become 'suspended' between the material's molecules in the process. While some similar forces are at work here, it is different from capillary attraction, a process where glass or other 'solid' substances attract water, but are not changed in the process, e.g. water molecules becoming suspended between the glass molecules. Hygroscopic substances include sugar, honey, glycerol, ethanol, methanol, diesel fuel, sulfuric acid, methamphetamine, many salts (including table salt), and a huge variety of other substances. Zinc chloride and calcium chloride, as well as potassium hydroxide and sodium hydroxide (and many different salts) are so hygroscopic that they readily dissolve in the water they absorb: this property is called deliquescence (see below). Sulfuric acid is not only hygroscopic in high concentrated form, its solutions are hygroscopic down to concentrations of 10 Vol-% or below. More commonly, a hygroscopic material will tend to become damp and "cake" when exposed to moist air (such as salt in salt shakers during humid weather). Because of their affinity for atmospheric moisture, hygroscopic materials might necessarily be stored in sealed containers. When added to foods or other materials for the express purpose of maintaining moisture content, such substances are known as humectants. Materials and compounds exhibit different hygroscopic properties, and this difference can lead to detrimental effects, such as stress concentration in composite materials. The amount a particular material or compound is affected by ambient moisture may be considered its coefficient of hygroscopic expansion (CHE) (also referred to as CME, coefficient of moisture expansion) or coefficient of hygroscopic contraction (CHC)—the difference between the two terms being a difference in sign convention and a difference in point of view as to whether the difference in moisture leads to contraction or expansion. A common example where difference in this hygroscopic property can be seen is in a paperback book cover. Often, in a relatively moist environment, the book cover will curl away from the rest of the book. The unlaminated side of the cover absorbs more moisture than the laminated side and increases in area, causing a stress that curls the cover toward the laminated side. This is similar to the function of a bi-metallic strip. Inexpensive gauge-type hygrometers frequently seen domestically make use of this principle. The similar-sounding but unrelated word hydroscopic is sometimes used in error for hygroscopic. A hydroscope is an optical device used for making observations deep under water.

I'll be using geoengineering from now on.
You asked me to focus on Solar Radiation Management, with particular attention to stratospheric sulfate aerosols, and marine cloud whitening.
The geoengineering idea is to inject a “source” for aerosols into the same region of the atmosphere that volcanoes tend to inject the gas. I use the word “source” to refer to either a gas like sulfur dioxide or to inject sulfuric acid directly... scientists have occasionally considered using other kinds of particles to do geoengineering.
Sulfuric acid is not only hygroscopic in high concentrated form, its solutions are hygroscopic down to concentrations of 10 Vol-% or below.

Before jumping in further, I want to get past a few “buzzwords” immediately. From here on I will often replace the term “Solar Radiation Management” with the word “geoengineering”. And I will often loosely refer to the “changes in the amount of energy entering or leaving some part of the planet because of some climate factor” as a “forcing”. So ... there is another forcing associated with Solar Radiation Management.
I don’t think scientists know enough today about geoengineering, and so I don’t think we are ready for “deployment”
