Reservoir Water Level Monitoring Using CYGNSS's Level-1 Observations

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The use of measurements from NASA's CYGNSS mission for the mapping of inland water bodies has been extensively demonstrated in past works. Despite this progress, the use of CYGNSS measurements for monitoring dynamic properties of water bodies ...

Daily 9-km Soil Moisture Retrieval With Reconstructed GNSS-R Observations

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Spaceborne global navigation satellite system-reflectometry (GNSS-R) observations are effective for extensive monitoring of soil moisture (SM). Reliance on gridded data from other remote-sensing systems is the general way of GNSS-R SM retrieval ...
