This data set contains measurements of reflectivity and derived estimates of snowfall rate made by a Precipitation Occurrence Sensor System (POSS) that is deployed at Summit Station, Greenland as part of the Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) Project. The POSS makes measurements in an approximately one cubic meter volume just above the sensor and is designed to quantify the amount of precipitation reaching the surface. Data files contain timeseries of the observed radar reflectivity and other supporting radar measureables as well as the derived snowfall rate in mm/hr. Detailed information on these parameters and other aspects of the dataset are included in the netCDF header information for each file. The POSS is operated by Matthew Shupe at the University of Colorado and is on loan from Environment Canada. Field operations are supported by the National Science Foundation's Arctic Observing Network (AON) Program.
