This dataset contains a time-series collection of daily gridded
Northern Hemisphere tropospheric data on a 47-by-51
polar-stereographic grid. These grids have been assembled by DSS
from the analyses of various operational models and meteorological
projects, and they cover the overarching period from January 1946
forward, although periods for individual parameters and levels will
vary. The grids continue to be updated with new data.
Available parameters include sea-level pressure, surface and
sea-surface temperatures, and upper-level geopotential height,
temperature, wind, and vertical motion at levels from 1000 millibars
up to 100 millibars.
