GPM GV AIO2 UConn

This instrument utilizes a non-aspirated temperature sensor and sonic anemometer integrated with a precision thermistor temperature sensor, fast-response capacitive relative humidity sensor, and a state-of-the-art barometric pressure sensor.

It also includes an internal flux-gate compass that allows for automatic alignment of wind direction to magnetic north, regardless of the sensor’s orientation. These data were collected during the GPM Ground Validation Field Campaign at the University of Connecticut, which provided an unprecedented set of wintry precipitation observations from multiple traditional and novel precipitation measurement instruments that can be used for validating ground-based and satellite remote sensing observations.
