GHRC published the guide for the GPM Ground Validation Environment Canada (EC) Passive Microwave Radiometer and Soil Moisture-Temperature Data GCPEx dataset. The data includes microwave brightness temperatures, snow and soil/snow-air interface (ground surface temperatures), soil surface temperatures, and soil volumetric water content acquired by multiple instruments – a passive microwave radiometer, a water content reflectometer, thermistors, and a soil moisture probe – during the GPM Cold-season Precipitation Experiment (GCPEx) at Environment Canada’s Centre for Atmospheric Research Experiments (CARE) in Ontario, Canada during the winter season 2011-2012.
