Abstract:

This dataset contains twice daily gridded Northern Hemisphere analyses from NCEP's operational model on 47-by-51 and 65-by-65 polar-stereographic grids centered on the North Pole. Available parameters include geopotential height, temperature, stream functions, thickness, and vertical velocity for various levels and layers through the troposphere.

NCEP prepared the 65-by-65 analyses, and were an advancement over the 47-by-51 "B3" analyses. Later NCEP made global analyses, from which the 65-by-65 analyses were interpolated. To continue the 47-by-51 analyses, NCAR/CISL/DSS extracted them from the 65-by-65 grid.
