Passive microwave sensors are key sensor payloads on many operational satellites, including those operated by NOAA and EUMETSAT – the Advanced Microwave Sounding Unit (AMSU) and the Microwave Humidity Sounder (MHS). Over the past decade, satellite-based high frequency measurements at and above 150 GHz (including those near the 183 GHz water vapor absorption band) have become extremely useful for the retrieval of several parameters, including precipitation rate and snowpack properties. In order to advance our understanding of the relationship between these parameters and the emitting microwave energy (and to advance radiative transfer model development), a sensor that can be used on the ground (either pointing upward or downward) which takes measurements at these high frequencies needs to be developed – presently, such sensors typically make measurements at 90 GHz or lower.
