district forecast
解釋
區域預報-
Especially, global transformation, the water balance, carbon balance and drought forecast in district, etc, which all require quantitative surface flux. by all appearances, these fluxes all do n ' t need to be distributed in spots, but in area
尤其全球變化、區域水分平衡、碳平衡和區域旱災預報等等都需要定量的地表通量信息（輻射通量、顯熱通量、潛熱通量、土壤熱通量） 。顯然，這些通量均要求區域分佈的而不是單點數據。 -
