TRMM Sees Sandy As A Hurricane Again

Yesterday Sandy dropped to tropical storm intensity but the National Hurricane Center (NHC) decided on October 27,2012 at 1500 UTC (11 AM EDT) that Sandy was again a minimal hurricane. The rainfall analysis on the right was made from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data collected when TRMM flew above less than an hour later at 1552 UTC (11:52 AM EDT). This analysis includes some rainfall that was beyond the reach of land based radar observations.

Hurricane Sandy Raining Over Atlantic Coast

Hurricane Sandy, located east of the Carolina's, has maintained minimal hurricane strength while following it's forecast track toward the northeast. The National Hurricane Center (NHC) predicts that Sandy will make a turn toward the Mid-Atlantic coast tomorrow. As a post-tropical low Sandy is then predicted to produce extremely heavy rainfall and dangerously high winds over a large area of the North-East after landfall. The TRMM satellite collected data when it flew over hurricane Sandy again today at 1456 UTC (10:56 AM EDT). An analysis of rainfall from TRMM's Microwave Imager (TMI) and

Deadly Super Storm Sandy's Rainfall

The reported death toll from hurricane Sandy's flooding and high winds has now reached above 120. Over 70 deaths were caused by Sandy in the Caribbean and recent reports bring the total to greater than 50 in the United States. Much of the recent deadly flooding along the northeastern United States coastlines was caused by super storm Sandy's storm surge. Strong winds from Sandy persistently pushed Atlantic ocean waters toward the coast. High tides that occurred at the same time also magnified the effects of the storm surge. Some flooding was also caused by long periods of heavy rainfall that

GPM Completes First Dry Run

By Ellen Gray , NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 10/17/12) NASA's Global Precipitation Measurement (GPM) Core Observatory satellite went through its first complete comprehensive performance test (CPT), beginning on Oct. 4, 2012 at NASA's Goddard Space Flight Center in Greenbelt, Md. The testing ran twenty-four hours, seven days a week and lasted ten days as the entire spacecraft was put through its paces. "This is the first time we've gotten to see the observatory all put together, running the way it's supposed to be running in flight," said CPT
