NASA Wraps Up Ontario Snow Observing Research Campaign

For six weeks in Ontario, NASA scientists and engineers lead a field campaign to study the science and mechanics of falling snow. The datasets retrieved will be used to generate algorithms which translate what the Global Precipitation Measurement (GPM) Core satellite “sees” into precipitation rates, including that of falling snow. Ground validation science manager Walt Petersen gives a summary of the GCPEx field campaign. Field campaigns are critical in improving satellite observations and precipitation measurements.
