Abstract

Soil moisture has been particularly difficult to measure and map using conventional ground-based point sampling. Microwave remote sensing–based soil moisture retrieval has been demonstrated using tower and aircraft instruments. The translation of this approach to satellites and the implementation in hydrologic applications has been limited by both the technology and the satellite systems that were available. Recent developments in both science and associated technologies now make the exploitation of the microwave region for soil moisture mapping feasible. A number of new and potential satellite missions are reviewed and evaluated for soil moisture applications.
