Vikleda combining the strength of active microwave, passive microwave and optical/thermal data.

We have developed the innovative algorithm named Vikleda to estimate soil moisture from multi-satellite data having all-weather capabilities. The algorithms have been tested with various satellite data (e.g. RADARSAT-2, RISAT-1, ENVISAT, Sentinel-1 and ALOS-PALSAR). The algorithm combines the strength of active and passive microwave to provide a higher spatio-temporal resolution soil moisture product. Further, the algorithms do not require site-specific calibration and hence can be easily applied over larger areas. By combining multi-satellite data, we provide customized daily (surface and root zone) soil moisture products up to 30 m spatial resolution.
