Title

NCEP Daily Northern Hemisphere Tropospheric Analyses for 1973 January to 1997 March

Alternative title(s)

d066000

Abstract

<p>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.</p> <p>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.</p>
