"Operational Soil Moisture Remote Sensing in Support to Water Hazards Monitoring";
Talk: ISA/UN-SPIDER workshop, Building Upon Regional Space-based Solutions for Disaster Management and Emergency Response,
Soil moisture plays an important role in the global water cycle. It controls the exchange of water and heat energy between the land surface and the atmosphere. The amount of precipitation that runs into nearby streams and rivers are strongly affected by soil moisture. In addition soil moisture information can be used for reservoir management, early warning of droughts, irrigation scheduling, and crop yield forecasting.
Microwave remote sensing instruments operated at low frequencies (1-10 GHz) have the potential of soil moisture retrieval because of the large dielectric contrast between dry and wet soil at these frequencies. The goal of our research group at the Institute of Photogrammetry and Remote Sensing (IPF) in Vienna University of Technology (TU-Wien) is to develop practical methods for the retrieval of hydrologic parameters from radar satellites. We use the scatterometers onboard ERS and MetOp satellites for global monitoring of soil moisture providing data continuity from 1991 until 2020. Based on the TU-Wien soil moisture retrieval algorithm, an operational near real time processor for the MetOp ASCAT is implemented at EUMETSAT's central processing facility. Additionally, as a part of SHARE project (ESA funded project) we use the ASAR Global Monitoring Mode of the ENVISAT satellite to extract an experimental soil moisture product and a scaling layer containing correlation information between local and regional backscatter.
