All files have a .a extension. So, a filename like 80730595.a would be data for site 8073 during May of 1995. There is also one file "avglistYY" in each year directorywhich contains the correct AGO site name,Latitude, Longitude, and Elevation for each file for every year. Like our other ten-minute data, a couple of these stations have 5 digit ID numbers. In order to maintain consistent file name structures, the leading digit is removed from the ID for use with the file names and file headers. Though data for AGO-1 (20655) for example, would be in file name 0655mmyy.a, and the header would appear as "MMM YY Station : 0655 AGO-1", it is important to remember that the station's ID is in fact 5 digits. The data are uncorrected; ie. they still have bad data points. They have been taken directly from the originally transmissions, though an effort was made to remove obnoxious extremes of data. Subtle errors may still exist in the averages; more refinements may be possible as this data is studied. The datasets are organized in ten-minute average intervals, with six columns as follows: each file has a two line header, followed by the columns of data. The columns are, from left to right: julian day, ten minute interval marker, temperature, pressure, wind speed, and wind direction. The ten minute interval marker is a number between 1 and 144 representing time: 1 is 00:00, 2 is 00:10, 3 is 00:20, 7 is 01:00, and 144 is 23:50. All times listed are GMT and missing data are indicated as 444.0. Wind directions listed are the direction the wind is blowing from, from 0 to 360 clockwise (thus 90 degrees is east, 180 is south and 270 is west).
