A weak tropical cyclone locally called Irina caused flooding over northern Madagascar less than two weeks after deadly flooding by Tropical Cyclone Giovanna . The lastest tropical cyclone didn't have very strong winds when it passed over the coastal city of Vohemar on Madagascar's northeastern coast but street flooding was reported. The rainfall analysis above was made at the Goddard Space Flight Center using data from a near-real time Multi-satellite Precipitation Analysis (TMPA). TRMM-based near-real time Multi-satellite Precipitation Analysis (TMPA) data are used to monitor rainfall over

Joe Munchak is a scientist at Goddard Space Flight Center who specializes in remote sensing of snow. This week he writes from the air in the DC-8 out of Bangor, Maine. 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

View on Youtube This video shows a glimpse of operations during the NASA Global Precipitation Measurement (GPM) Cold Season Precipitation Experiment (GCPEx) during a heavy snow event on 18 February 2012 Steve Nesbitt is an assistant professor of atmospheric sciences at the University of Illinois at Urbana-Champaign. 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
