This app allows the user to visualize soil moisture estimates from Sentinel 1 activate microwave satellite observations. The app generates time series of average soil moisture estimates over a region of interest selected by the user. The retrieval algorithm was calibrated using in situ observations in the region of Millbrook, New York, one of the calibration/validation sites for the NASA Soil Moisture Active and Passive satellite mission (SMAP). NASA has launched SMAP to collect key information on soil water content on a global scale. While SMAP has proven to be reliable in collecting large-scale soil moisture data, it is necessary to continue the validation of the product using in situ observations. At the local test site in Millbrook, New York, in situ observations of soil moisture are continuously collected and compared to satellite estimates.
This Google Earth Engine application was developed by i-SMART laboratory team at Stevens Institute of Technology with a strong contribution from two undergraduate students: Tyler Chepetine and David Valle-Montesdeoca
