Use of VIIRS Day-Night Band Imagery in Response to Hurricane Sandy Recovery Efforts
In late October 2012, widespread strong winds, torrential rain, coastal flooding, and other effects of Hurricane Sandy contributed to widespread power outages throughout the northeastern United States. In response to this disaster, SPoRT provided SNPP VIIRS day-night band imagery and an experimental, false color blackout composite. SPoRT's experimental "blackout composite" of pre-storm and post-event imagery helped to identify missing lights in a single image. Through collaboration with NASA's Applied Sciences Disasters Program, daily composites were provided to the United States Geological Survey's Hazards Data Distribution System, where they were then distributed to the Department of Defense (DoD) Joint Task Force-Civil Support (JTFCS).

SPoRT has partnered with CIRA to transition their total precipitable water (TPW) product to the NWS. TPW is a measure of the amount of water in an entire column in the atmosphere, including near the surface which most conventional water vapor imagery misses, assisting in flood prediction. The image above comes from 19 August 2008 as Tropical Storm Fay crossed south Florida. The purple region to the east of Florida has the greatest water content as was associated with the part of the storm that dumped record rainfall in Melbourne, Florida.
