The following is a description of the global surface summary of day product produced by the National Climatic Data Center (NCDC) in Asheville, NC. The input data used in building these daily summaries are the Integrated Surface Data (ISD), which includes global data obtained from the USAF Climatology Center, located in the Federal Climate Complex with NCDC. The latest daily summary data are normally available 1-2 days after the date-time of the observations used in the daily summaries. The online data files begin with 1929, and are now at the Version 7 software level. Over 9000 stations' data are typically available. The daily elements included in the dataset (as available from each station) are: Mean temperature (.1 Fahrenheit) Mean dew point (.1 Fahrenheit) Mean sea level pressure (.1 mb) Mean station pressure (.1 mb) Mean visibility (.1 miles) Mean wind speed (.1 knots) Maximum sustained wind speed (.1 knots) Maximum wind gust (.1 knots) Maximum temperature (.1 Fahrenheit) Minimum temperature (.1 Fahrenheit) Precipitation amount (.01 inches)
DETAILS/FORMAT Global summary of day data for 18 surface meteorological elements are derived from the synoptic/hourly observations contained in USAF DATSAV3 Surface data and Federal Climate Complex Integrated Surface Data (ISD). Historical data are generally available for 1929 to the present, with data from 1973 to the present being the most complete. For some periods, one or more countries' data may not be available due to data restrictions or communications problems. In deriving the summary of day data, a minimum of 4 observations for the day must be present (allows for stations which report 4 synoptic observations/day). Since the data are converted to constant units (e.g, knots), slight rounding error from the originally reported values may occur (e.g, 9.9 instead of 10.0). The mean daily values described below are based on the hours of operation for the station. For some stations/countries, the visibility will sometimes 'cluster' around a value (such as 10 miles) due to the practice of not reporting visibilities greater than certain distances. The daily extremes and totals--maximum wind gust, precipitation amount, and snow depth--will only appear if the station reports the data sufficiently to provide a valid value. Therefore, these three elements will appear less frequently than other values. Also, these elements are derived from the stations' reports during the day, and may comprise a 24-hour period which includes a portion of the previous day. The data are reported and summarized based on Greenwich Mean Time (GMT, 0000Z - 2359Z) since the original synoptic/hourly data are reported and based on GMT. As for quality control (QC), the input data undergo extensive automated QC to correctly 'decode' as much of the synoptic data as possible, and to eliminate many of the random errors found in the original data. Then, these data are QC'ed further as the summary of day data are derived. However, we expect that a very small % of the errors will remain in the summary of day data. The data are strictly ASCII, with a mixture of character data, real values, and integer values. Following is the data format: First record--header record. All ensuing records--data records as described below. All 9's in a field (e.g., 99.99 for PRCP) indicates no report or insufficient data.

If you want a copy to study private message me and I will gladly mail you one. I will even pay for the postage. If someone knows how to upload these to the web let me know I will gladly do it. They are a lot better than the degraded 19 MB files that are on Youtube.

And I was wondering if you could not post all the previous threads on this case.

I think uploading them to an internet sharing service is probably the best idea. About 400 to 500 MB each.
I have been on the internet since the beginning but have yet to upload a file that size.

Personally I'm very grateful to elevenaugust for posting those links.
I think those links add considerably to this thread.
I have no problems with a new thread if it seeks to add to (rather than ignore) what has been said before, but providing those links to previous discussions may help avoid time being wasted reinventing the wheel.

Secondly, it has already been proven to be of a boat on the water here:

It's not real, it's not a UFO, we can put this Turkey case to rest once and for all.

The case totals over 26 seperate days.
Nothing has been proven to be a boat yet.... still waiting...
