GPM Cold Season Precipitation Experiment (GCPEx)

NASA is currently flying an airborne science laboratory above Canadian snowstorms to tackle
a difficult challenge facing the upcoming Global Precipitation Measurement (GPM) satellite mission -- measuring
snowfall from space. Working with Environment Canada, NASA's GPM Cold-season Precipitation Experiment (GCPEx)
is measuring light rain and snow in Ontario from Jan. 17 to Feb. 29.
