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，通过一系列塔架和机载现场实验，证明 P 波段辐射计能力可以远程感知顶部约 15 厘米的土壤湿度层。面对极端气候变化，近地表层的及时土壤湿度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 波段辐射计的顶部约 5 厘米的土壤层。该项目预计将为农民提供他们需要的土壤湿度数据，以优化他们的可用水资源，从而最大限度地提高粮食产量
