CryoRad: a mission concept based on Low Frequency Wideband Radiometry for Remote Sensing of the Cryosphere
Living Planet Symposium, 23-27 May 2022, Bonn, Germany Microwave sensors, both active and passive, are particularly suitable for observing polar regions because of their insensitivity to solar illumination and cloud coverage. However, most microwave sensors are sensitive to surface or near-surface p...
