February 29 marked the last day of the GPM Cold Season Experiment. After six weeks of no snow, light snow, rain, and some nice heavy snowstorms, the GCPEx team is heading home.

They captured a wide array of different types of snow and rain from Eastern New York as the DC-8 flew in from Maine to north of the CARE site in Huronia and Georgian Bay, off of Lake Huron

He studies clouds and precipitation using satellite data and ground based and aircraft observations in projects world wide. Using NASA and other measurements in tropical storms, and mid-latitude cyclones, his research group works to improve the understanding of precipitation
Chris Kidd is a hydrologist at Goddard Space Flight Center. This week he is at the CARE site in Ontario and writes to us about this week's flights. Although the excitement of the lake-effect snow last weekend was welcome, in contrast this week was somewhat benign. There were a number of good opportunities identified in the model forecasts that didn’t really materialize, leaving us with a number of, although marginal, still useful events.

In the CARE operations trailer monitoring weather conditions during the DC-8 flights on 6 February 2012 at approximately 9pm EST. Gail Skofronick-Jackson is the Deputy Project Scientist for GPM at Goddard Space Flight Center in Greenbelt, Md. She specializes in the remote sensing of snow, and is currently the mission scientist for the campaign at the CARE ground site in Ontario, Canada. She writes to us about a night flight on February 6 and the snow that didn't show. Models showed quickly developing snow from 9-10pm EST tonight (6 Feb 2012). We are at 9:22 and we don't yet see snow in the
