This joint Navy and Air Force study of the upper atmosphere is based on 1980-85 twice daily gridded analysis produced by the European Centre for Medium Range Weather Forecasts. Included are global analyses by 1 Mean atmospheric temperaturestandard deviation, 2 mean geopotential height standard deviation, 3 Mean atmospheric densitystandard deviation, 4 Height and vector standard deviation. All data is for 13 pressure levels - 1000, 850, 700, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30 mb. In addition, analyses of 5 Mean dew pointstandard deviation - levels 1000 through 300 mb, 6 Jet streams means scalar speed - levels 500 through 30 mb. Also included are global 5 degree grid point wind roses for the 13 pressure levels.
