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.
More information on the GCPEx Experiment can be found at https://ghrc.nsstc.nasa.gov/home/field-campaigns/gcpex.
