JPSS Flood Maps Assist with Flooding in Baton Rouge
JPSS Visible Infrared Imaging Radiometer Suite flood maps were deployed in Baton Rouge, Louisiana when heavy rains and massive flooding ravaged the state. In August 2016, heavy downpours dumped over four trillion gallons of rain over parts of Louisiana. VIIRS downscaled 30-m flood maps of Baton Rouge served as one of the primary data sources for FEMA officials and ultimately helped them investigate flood extent and inundation, determine areas of damage, and aid in flood response, recovery and mitigation. Flood maps provide high-resolution detail over vast areas. This information allows teams on the ground to plan for evacuations and determine where to focus their recovery efforts.
JPSS Satellites Map Floods in Louisiana from Hurricane Laura
The Suomi NPP and NOAA-20 satellites passed directly over the Louisiana/Texas coastline at 2:08pm Thursday, Aug. 27, 2020, getting a clear overhead look at the extent of flooding after Hurricane Laura slammed into the coast early that morning with hurricane-force winds and destructive storm surge.
The algorithm for this map takes the satellite data of floodwater at a 375-meter resolution, and, using known terrain and surface elevations, gives a higher resolution (30-meter) estimate of flood extent within each satellite image pixel. In this map, you can see storm surge flooding from Creole to Holly Beach, covering most of Cameron Parish, where the hurricane made landfall.
Flood maps like this one can be used by FEMA and other emergency responders to help with rescues and other emergency responses.
Northern Gulf Institute (NGI) - Louisiana State University
Louisiana State University is a partner institution of the NGI. NGI conducts high-impact research and education programs in the Gulf of Mexico region. Many of the research projects are providing new and improved tools and capabilities in support of NOAA’s goals including Healthy Oceans, a Weather Ready Nation, and Resilient Communities.
