Tracers are gases or powdered materials injected into the atmosphere
What It Is Used For
ARL’s Atmospheric Tracer Technology provides data neccesary to develop, test, and improve dispersion models and air quality monitoring systems. Atmospheric dispersion models are primary tools used by emergency managers and first responders to determine appropriate responses (e.g., approach routes, evacuation routes, shelter inplace) to chemical, biological, and nuclear accidents or incidents. Dispersion models also are used by regulatory agencies to determine appropriate pollutant emissions controls. Dispersion models must be tested (validated) with “real data” to detemine their accuracy. Since actual toxic materials cannot be released into the atmosphere, surrogate benign material (tracers) that mimic a real threat, such as those described here, are used instead.
Why It Is Important
Understanding how the atmosphere transports and disperses materials released into the air is essential to understanding and dealing with important problems such as air pollution or the accidental (or intentional) release of hazardous material. For example, Homeland Security experts now envision terrorist threat scenarios whereby chemical, biological, and nuclear weapons are used in densely populated urban centers for maximum impact. Atmospheric tracer experiments yield a host of critical information that are then used to determine chronic and acute exposure risks to humans if such an event should occur.
1. Pentagon Shield. A small atmospheric tracer study at the Pentagon has now expanded into a large study that will involve 8 of ARL’s 10 real-time SF6 (sulfur-hexaflouride) analyzers and all 100 of our bag samplers. The study now includes an indoor component that will use both real-time analyzers and bag samplers. The changes in scope occurred with very short lead time. This has required FRD staff to increase the focus on preparations. We are on schedule and the deployment will be May 1-10. [email protected] & staff
Preparations for the Pentagon Shield project have been extensive. The SF6 continuous analyzers have been upgraded, tested, and conditioned. Special lab carts will be used to deploy the analyzers inside the Pentagon. Gas Lab personnel are testing the Programmable Integrating Gas Samplers (PIGS) and conducting an aging study to verify that the samples will not be compromised during shipping from Washington, D.C. to Idaho. Planning for the project has been challenging because of changing requirements and a tight schedule but preparations are proceeding smoothly. [email protected], Debbie Lacroix

Calibration of Measuring Instruments
The droplet size and output concentration of ATM aerosol generators makes them suitable for dispersing PSL size standards for instrument calibration (particle sizers, optical particle counters and photometers). Filter Testing Product quality assurance and safety aspects require regular testing of high-efficiency filters, certification of laminar air flow boxes and clean room measurements in general.
For this purpose a suitable test aerosol needs to be generated as atmospheric aerosols or ambient air do not have stable particle size or concentration. VDI-guideline 3491 suggests using aerosol generators to produce test aerosols in a definite manner. Aerosol generators producing highly concentrated aerosols, whose mean particle size is close to the most penetrating particle size (MPPS) allow leak locations to be found in a quicker time. Using an oil aerosol material (DEHS, DOP, PAO, Emery 3004) provides long term stability due to the lack of evaporation which can over time alter the size of aerosols generated from a solution with volatile solvent.

....binoculars to get a closer look at one. You can literally see the vapor coming out of the nozzles on the plane....

CHEMICAL trails come from the engine turbines of a plane, and form clouds which can en mass entirely cover a portion of the sky.
don't believe me? go ahead, spend an hour or so watching real planes in the very real sky above your real head.

...These planes, release EXHAUST from burning gasses like every other plane, but normally EXHAUST Does NOT last more than a minute in the sky, if it does, it'd be a real thin stream of exhaust.
Now compare that with a chem-trail plane. The "exhaust" from it, lasts longer than an hour, or up to an hour, maybe even a little less than an hour. I don't know, never really timed it.... Thanks for reading.
