![]() This flood proxy map should be used as guidance to identify areas that are likely flooded, and may be less reliable over urban and vegetated areas. This map was cross-validated with ARIA’s earlier flood proxy map. ![]() Media reports provided anecdotal preliminary validation. The map, which was pushed to FEMA’s SFTP server (and is available to download), depicts areas of the Carolinas in light blue pixels that are likely flooded. The Advanced Rapid Imaging and Analysis (ARIA) team at NASA’s Jet Propulsion Laboratory in Pasadena, California, created a flood extent map from Sentinel-1 synthetic aperture radar data acquired 12 hours after Hurricane Florence made landfall. These data meet the timely needs of applications such as numerical weather and climate prediction, forecasting and monitoring natural hazards, agriculture, air quality, and disaster relief.ĪRIA FLOOD EXTENT MAPS These images, derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellites, operated by the European Space Agency, were taken before Florence, on September 02, 2016, and 12 hours after the storm’s landfall at 7:06 PM local time on September 14, 2018. LANCE leverages existing satellite data processing systems in order to provide such products from select EOS instruments. NASA’s Land, Atmosphere Near real-time Capability for EOS (Earth Observing System) (LANCE) provides data and imagery from Terra, Aqua, Aura, Suomi NPP, and GCOM-W1 satellites in less than three hours from satellite observation to meet the needs of the near real-time applications community. LAND, ATMOSPHERE NEAR REAL-TIME CAPABILITY FOR EOS LANCE imagery of water vapor, precipitation, and wind speed in Hurricane Florence from Sept. Here’s a snapshot of some of the ways NASA has been monitoring the storm and its repercussions: Products can be found on the NASA Disasters Mapping Portal. The space agency’s Earth Science Disasters Program is sparing no available resource in working to keep disaster responders and agencies such as FEMA and the National Guard informed with the latest information to assist in decisions on everything from evacuations to supply routes and recovery estimates. NASA has been tracking Florence since it began moving toward the East Coast of the United States and continued to monitor the storm as it inched across the Carolinas and farther inland. ![]() GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency.The VIIRS instrument on the joint NASA/NOAA Suomi NPP satellite observed Hurricane Florence as it developed in the Atlantic Ocean and made landfall in North Carolina on Sept. GPM data is part of the toolbox of satellite data used by forecasters and scientists to understand how storms behave. The GPM Microwave Imager sees through the tops of clouds to observe how much and where precipitation occurs, and the Dual-frequency Precipitation Radar observes precise details of precipitation in 3-dimensions. The GPM Core Observatory carries two instruments that show the location and intensity of rain and snow, which defines a crucial part of the storm structure – and how it will behave. The storm later restrengthened into a hurricane. At that time, the storm was experiencing strong wind shear. NASA's Global Precipitation Measurement mission or GPM core observatory satellite flew over Tropical Storm Florence on September 7, 2018. Frozen precipitation is shown in cyan and purple. Shades of green to red represent liquid precipitation. A slicing plane moves across the volume to display precipitation rates throughout the storm. As the camera moves in on the storm, DPR's volumetric view of the storm is revealed. GPM passed over Tropical Storm Florence on September 7, 2018.
