Skillful seasonal water and crop forecasts could do much to help cope with drought and water-related food crises. Recent advances in hydrological modelling and satellite remote sensing of surface soil moisture, landscape water storage and vegetation biomass have created a great opportunity to produce such forecasts over large areas. This project will exploit that opportunity by assimilating the satellite observations into a global water and vegetation forecasting model. The resulting improvement in seasonal forecasts of stream flow, soil moisture and crop production will be quantified and compared to the limited forecasts that are currently available.

巧妙的季节性水和作物预报可以在很大程度上帮助应对干旱和与水有关的粮食危机。在地表土壤水分、地貌蓄水量和植被生物量的水文模拟和卫星遥感方面的最新进展为在大范围内进行这种预报创造了极大的机会。该项目将利用这一机会，将卫星观测同化为全球水和植被预报模型。随之而来的河流流量、土壤湿度和作物产量季节性预报的改善将被量化，并与目前可用的有限预报进行比较。
