NASA adds up Hurricane Sandy's rainfall from space

Nov 01, 2012
This TRMM rainfall analysis indicates that the heaviest rainfall totals of greater than 260mm (10.2 inches) were over the open waters of the Atlantic Ocean. Rainfall totals of over 180mm (~ 7 inches) are also shown over land in many areas near the Atlantic coast from New Jersey to South Carolina.

NASA's Tropical Rainfall Measuring Mission, or TRMM, satellite acts as a rain gauge in space as it orbits the Earth's tropics. As TRMM flew over Hurricane Sandy since its birth on Oct. 21 it was gathering data that has now been mapped to show how much rain the storm dropped along the U.S. eastern seaboard.

Much of the recent deadly flooding along the northeastern United States coastlines was caused by super storm Sandy's storm swell. 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 swell. Some flooding was also caused by long periods of heavy rainfall that made rivers and streams overflow their banks.

The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) is done at NASA's Goddard Space Flight Center in Greenbelt, Md. The MPA monitors rainfall over a large area of the globe (from 60 degrees North latitude to 60 degrees South latitude). MPA rainfall totals over the eastern United States were calculated for the period from October 24-31, 2012 when super storm Sandy was making it's catastrophic transit through the area.

The indicated that the heaviest rainfall totals of greater than 260mm (10.2 inches) were over the of the Atlantic Ocean. Rainfall totals of over 180mm (~ 7 inches) occurred over land in many areas near the Atlantic coast from New Jersey to South Carolina.

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.

NOAA's Hydrometeorological Prediction Center issued their last advisory on Sandy's remnants on Oct. 31, stating that "multiple centers of circulation in association with the remnants of Sandy can be found across the lower Great Lakes."

A from NOAA's GOES-13 satellite at 1:31 p.m. EDT on Nov. 1, 2012 showed the remnant clouds from Sandy still lingered over the Great Lakes and stretched east to New England and north into Canada.

The book on this super storm is now closed, though the clean-up will continue for a long time to come.
