Soil moisture time series from GNSS interferometric reflectometry (WP H3)
Soil moisture is a geophysical key observable for predicting floods and droughts, modelling weather and climate and optimizing agricultural management. Currently available in-situ observations are limited to small sampling volumes and restricted number of sites, whereas measurements from satellites lack spatial resolution. Global navigation satellite system (GNSS) receivers can be used to estimate soil moisture time series at an intermediate scale of about 1000 m2. In this case study, GNSS signal-to-noise ratio (SNR) data at the station Sutherland, South Africa, are used to estimate near-surface soil moisture variations between January 1, 2008 and September 1, 2014. The results capture the wetting and drying cycles in response to rainfall. The data are daily averages based on signals of 6 GPS satellites. The GNSS derived soil moisture was validated by Time Domain Reflectometry (TDR) in-situ observations.
