NCEP Global Tropospheric Analyses on 145x37 2.5 degree grids, one for each hemisphere, 1976Jul01-1997Apr12. The Flattery analysis method was used through 1978Sep21. It forced a relationship between heights and winds which causes the zonal mean meridional wind at every level to be zero. This also caused other problems with winds in equatorial areas. The optimal analysis (OI) method (12 layer) started 1978Sep22. In 1985Apr the Medium Range Forecast (MRF) model started, with 18 layers. Analyses include geopotential height, temperature, wind (u- and v-components) and potential temperature. In more recent years the temperature analyses are derived from thickness temperatures.
