The flooding was some of the worst ever in the state, resulting in a state of emergency. Tens of thousands of people were evacuated from their homes in the wake of this unprecedented event.

Throughout the course of August 12 (UTC) GPM captured the internal structure of the storm twice and GPM IMERG measured the rainfall accumulation on the ground.

NASA's GPM satellite is designed to measure rainfall using both passive microwave (GMI) and radar (DPR) instruments. DPR can observe 3D structures of radar signals reflected by rain and snow in a narrower swath.

IMERG is a NASA data product that combines data from 12 different satellites into a single seamless map. IMERG covers more of the globe than any previous precipitation data set and is updated every half hour.", "items": [], "extra_data": {} } ], "studio": "GMS", "funding_sources": [ "PAO" ], "credits": [ { "role": "Producer", "people": [ { "name": "Ryan Fitzgibbons", "employer": "USRA" } ] }, { "role": "Visualizer", "people": [ { "name": "Alex Kekesi", "employer": "Global Science and Technology, Inc." } ] }, { "role": "Scientist", "people": [ { "name": "George Huffman", "employer": "NASA/GSFC" }, { "name": "Stephen J.

In this close up of GPM's volumetric DPR data over Louisiana, a cutting plane materializes into view to show the inner structure of this giant storm system. From this view, one can clearly see the heavy amounts of rain in the center of the storm (depicted in yellow, orange, and red). The GPM data then dissolves away as time speeds up before slowing down again later on that same day. This time GPM captures a much larger swath of the storm. Dissolving in the cutting plane again reveals huge amounts of rainfall at this later time. As the GPM data dissolves away again, time speeds back up to show the rest of the rainfall accumulation partway through August 13.
