This TRMM satellite rainfall analysis indicates that the heaviest rainfall totals of greater than 260mm (10.2 inches) were over the open waters of the Atlantic Ocean.

A NASA satellite operating from a birds-eye view now has precise data on rainfall from Superstorm Sandy, when it showered cats and dogs.

Called the Tropical Rainfall Measuring Mission, the satellite usually acts as a rain gauge for much of the globe, but it managed to track Sandys staggering rainfall from the storms birth in the Atlantic Ocean on Oct. 21 to its days of destruction over the East Coast this week.

Having operated from about 250 miles above the earths surface, the satellite shows that thankfully for East Coast residents the worst rainfall occurred over the ocean, with 10.2 inches dumped into the Atlantic.

Still, Sandy did drop around 7 inches over much of the stretch of land from South Carolina to New Jersey. This can be seen on a new map created by NASA.

In New York, flooding from Sandy caused major damage throughout the city. Seven MTA subway tunnels were flooded, and homes and businesses throughout the region were shuttered because there was just too much water.

And two boys in Staten Island were also ripped from their mothers arms as floodwaters surrounded their SUV.
