Gelman's CAC Global Analyses, September 1978 to February 1998

This dataset contains global once-daily and monthly-mean gridded analyses for September 1978 to February 1998, which were produced by NMC's operational models. At mandatory levels from 1000mb up to 0.4mb, grids contain geopotential height and temperature. At the tropopause, grids contain pressure and temperature. Also included are total column ozone and upward flux of longwave radiation. The grid is a 65x65 polar-stereographic grid, centered on the Pole (North or South). Global coverage is provided by combining two grids, one for the Northern Hemisphere and one for the Southern Hemisphere. The Flattery analysis method was used through 26 July 1984, so the usefulness of grids in that period is suspect. After that time, the analysis method used was the same as for other NMC global archives.
