Global Climatic Data for Surface, 800 mb, 400 mb
This publication is part of a continuous effort to gather, in one common format, the most representative global climatologies of certain meteorological variables. The April global distributions of pressure, temperature, wind, and moisture have been taken from a variety of climatological sources and formats, for reconstruction at the surface, 800 mb, and 400 mb to facilitate comparison with integrations from the Mintz-Arakawa two-level model. These data are supplemented by presentations of the global distributions of cloudiness, planetary and surface albedo, long-wave radiation, evaporation, precipitation, and selected elements of the surface heat balance. All data are presented on a global grid of 4-deg latitude by 5-deg longitude, in the form of both tabulated values and machine-analyzed maps. The corresponding zonal and global averages are also given.
