GES DISC precipitation data tools view the vicious storm Ida

Hurricane Ida transformed to a tropical storm, then an extratropical low, then a powerful "nor'easter" that assaulted the Mid-Atlantic coast; GES DISC resources provide views and information for this storm, complemented by data from the NASA QuikSCAT satellite

TRMM precipitation data for November nor'easter "Ida"

GES DISC precipitation data tools view the vicious storm Ida

The Atlantic hurricane season is officially almost over, and it has been a quiet one, partly due to the influence of the moderate El NiƱo conditions in the Pacific Ocean, which are known to suppress hurricane formation in the Atlantic.    But one storm, Ida, was enough to make the season memorable.  Ida was actually born in the Caribbean Sea near Nicaragua, became a Gulf of Mexico hurricane, then weakened to a tropical storm before making landfall on the Florida Panhandle — and then as an extratropical low pressure system moved over to the Atlantic coast and re-intensified into a vicious "nor'easter" that assaulted and battered the Mid-Atlantic coast, causing hundreds of millions of dollars of damage and massive coastal erosion.

GES DISC satellite data tools provide excellent views of Ida's swath of rain and wind.   The Merged IR data in the GES DISC Hurricane Data Analysis tool was used to create the animated image below as Hurricane/Tropical Storm Ida approached landfall.

The next image is the accumulated rainfall from Ida as it became a low-pressure system and then became a destructive "nor'easter".  The data product used for this image is the TRMM 3-hourly precipitation data product, plotted with Giovanni, and averaged over the time span of November 10 to November 14.

It is important to note in the image above the heavy amount of rainfall in the Atlantic, east of the mouth of the Chesapeake Bay.   Rainfall can affect the retrieval of sea surface wind speed by the QuikSCAT satellite.    The image below is from the NOAA QuikSCAT near-real-time wind image site.    As can be seen, there are many wind vectors in black;  the image caption indicates that these wind data may be contaminated by rain.   The correlation between the amount of rain observed by TRMM and the black wind vectors is quite striking.  This synergy of data from different NASA satellites provides even more information to researchers examining the dynamics and destructiveness of severe storms.
