Technical Abstract: Soil moisture mapping using remote sensing will become a reality in this decade. Soil moisture has been difficult to measure and map using conventional ground based technologies. Microwave remote sensing based soil moisture retrieval has been demonstrated using tower and aircraft instruments, however the implementation of this approach on satellites has been limited by both technology and availability. Developments in both science and associated technologies now make the exploitation of the microwave region for soil moisture mapping feasible. A review of the basic principles, operational retrieval algorithms, aircraft applications, and current and future satellite missions are presented.
