Soil moisture is a highly critical resource for the Australian agricultural economy which is stressed by climate change. Daily monitoring of paddock scale soil moisture from space represents a powerful tool to inform land management, allowing accurate crop yield and pasture growth predictions. At the continental scale, soil moisture information will result in better weather, climate and extreme flood prediction skill and the ability to assess the effects of future climate change on Australia. It is therefore imperative that active-passive soil moisture retrieval algorithms be developed specifically for the Australian environment in order to take full advantage of the SMAP remote sensing mission when it is launched in 2012.

土壤水分对于受到气候变化压力的澳大利亚农业经济来说是非常重要的资源。从太空对围场规模的土壤湿度进行日常监测是为土地管理提供信息的强大工具，可以准确预测作物产量和牧草生长。在大陆尺度上，土壤湿度信息将带来更好的天气、气候和极端洪水预测技能，以及评估未来气候变化对澳大利亚影响的能力。因此，必须专门针对澳大利亚环境开发主动-被动土壤湿度反演算法，以便充分利用 2012 年启动的 SMAP 遥感任务。
