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 ...

MEASUREMENT MODEL OF IONOSPHERIC ELECTRON CONTENT WITH CYGNSS

, 2013
Global ionospheric imaging is currently limited by a lack of significant quantities of observations over the oceans. This deficiency of measurements arises because coverage from Global Navigation Satellite System (GNSS) remote sensing tools is typically ...

Time-Series Retrieval of Soil Moisture Using CYGNSS

, 2019
Time-series retrievals of soil moisture obtained from the Cyclone Global Navigation Satellite System (CYGNSS) constellation are presented. The retrieval approach assumes that vegetation and roughness changes occur on timescales longer than those ...
