This project aims to develop radiative transfer models to demonstrate that a P-band radiometer capability can remotely sense the top ~15cm layer of soil moisture, through a series of tower and airborne field experiments. Timely soil moisture information on this near-surface layer is critical to improved water management for food production in the face of extreme climate variability. Current satellite technologies are limited to the top ~5cm layer of soil using an L-band radiometer. This project is expected to give farmers the soil moisture data they need to optimise their available water resources to maximise food production

该项目旨在开发辐射传输模型，通过一系列塔式和机载野外实验，证明P波段辐射计的能力可以遥感土壤表层~15 cm的水分。在面对极端气候变化的情况下，及时掌握这一近地表土壤水分信息对于改善粮食生产的水管理至关重要。目前的卫星技术仅限于使用L波段辐射计的土壤表层~5厘米。该项目预计将为农民提供所需的土壤水分数据，以优化他们的可用水资源，使粮食产量最大化。
