Sea Surface and Atmosphere Conditions for Coherent Reflectometry: On the Impact of Sea Ice and Sea State
Coherently reflected GNSS signals are a valuable source for Earth observations. They find application in retrievals of sea surface height with centimetre-level precision as well as for estimation of soil moisture or sea-ice concentration. The application of coherent reflectometry is strongly affecte...
