U.S. Navy Northern Hemisphere Daily (and Monthly) Sea-Level Pressure and 500 mb Height Grids for 1946Jan to 1993Dec
The gridded daily sea-level pressure analyses in this dataset
were produced by the operational models of the U.S. Navy Fleet
Numerical Oceanography Center (FNOC). The data are arranged in
a 63x63 polar-stereographic grid covering the Northern
Hemisphere for the period January 1946 to December 1993. DSS
has produced a set of monthly grids from the dailies.
This dataset also includes daily 500mb geopotential height
grids for the period January 1946 to December 1955 on the same
polar-stereographic grid as the sea-level pressure data.
