NCEP Daily 65x65 Northern Hemisphere Tropospheric Analyses for 1973 January to 1997 March (and 47x51 subset, by DSS)

This dataset contains twice daily gridded Northern Hemisphere analyses from NMC's operational model on 47x51 and 65x65 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 65x65 analyses, and were an advancement over the 47x51 "B-3" analyses. Later NCEP made global analyses, from which the 65x65 analyses were interpolated. To continue the 47x51 analyses, NCAR/CISL/DSS extracted them from the 65x65 grid. This dataset is maintained by NCAR's Data Services Section (DSS). Please see the external link for data access.
