PRECIPITATION MEASUREMENT MISSIONS

GCPEx Campaign Blog

By Ellen Gray
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. The campaign ended with a big storm last Friday, February 24th, that put all three planes in the air over an eight hour period. They captured a wide array of different types 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.

Last time I wrote for the GCPEx blog, I was stationed in Barrie, Ontario with the ground team. I’ve since switched hats to that of CoSMIR Instrument Scientist. CoSMIR (Conically Scanning Millimeter Imaging Radiometer) is one of two instruments on the NASA DC-8 which is based out of Bangor, Maine – my home for the past ten days. With CoSMIR and the Airborne Precipitation Radar-2 (APR2), the DC-8 is acting as a simulator for the GPM satellite, looking down on the CARE ground site so...

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.
