Instrument

POSS
Precipitation Occurrence Sensor System

The Precipitation Occurrence Sensor System (POSS) is an X-band, continuous wave radar consisting of both a transmitter and receiver. It was originally designed by what is now the Meteorological Service of Canada and can be used to derive the type, rate, and drop size distribution of precipitation.
