NMC Global Tropospheric Analyses, tropopause subset
Listed in National Center for Atmospheric Research
NCEP Global Tropospheric Analyses on 2.5 degree grids, one for each hemisphere, from 1 July 1976 to 12 April 1997.
Description
The Flattery analysis method was used through 21 September 1978. 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 on 22 September 1978. In April 1985 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.
