Abstract: | The National Meteorological Center of the National Oceanic and Atmospheric Administration (NOAA) has archived global, daily synoptic analyses and computer gridded fields of geopotential height and temperature for 8 stratospheric pressure levels (70, 50, 30, 10, 5, 2, 1 and 0.4 mb) since the Autumn of 1978. More restricted analyses are available since 1964. The fields are discussed, with special emphasis on improvement of the data bases and analysis procedures. Included in the discussions are screening procedures for the climatological data base. Examples are given with regard to monthly mean energy, wind and hemispheric temperature patterns calculated as the initial development of a stratospheric dynamic climatology. |
