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

Originally the 47x51 grid was the one in which the B-3 analyses were done. These are now interpolated from the global analyses. Now NCEP interpolates the 65x65 grid from the global analyses. NCAR extracts the 47x51 subgrid (List A) from the full grid (List B).
