NMC B3 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 47 by 51 polar-stereographic grid centered on the North Pole.国家气象中心（NMC）在1963年8月至1972年12月期间，运行产生了这些针对不同对流层层次的每日网格化北半球分析数据。所包含的参数包括高层风速、地表温度、海平面气压、对流层顶压力和温度，以及以北极为中心的47×51极地斜视网格上的500毫巴相对湿度。
