NMC B-3 Daily Northern Hemisphere Analyses for 1963 August to 1972 December
NMC operationally produced these daily gridded Northern
Hemisphere analyses of various tropospheric levels for the
period August 1963 to December 1972. Parameters include
upper-level winds, surface temperature, sea-level pressure,
tropopause pressure and temperature, and 500mb relative humidity
on a 47x51 polar-stereographic grid centered on the North
Pole.
