The Moon as a diagnostic tool for microwave sensors

Posted on
3rd January 201729th July 2019

Microwave sensors are used to measure upper tropospheric humidity, but the temperature of the on-board calibration target may drift slowly over time making long-term measurements difficult. To solve this, we employ a second reference for calibrating measurements – the moon
