Camp Fire ARIA DPM 
Camp Fire ARIA DPM  The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas of Southern Cailfornia that are likely damaged (shown by red and yellow pixels) as a result of the Camp Fire in Northern California. The map is derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1 satellites, operated by the European Space Agency (...

Sentinel-1 Water Extent Imagery
Using data collected from the European Space Agency's (ESA) Sentinel-1B satellite, scientists at NASA's Marshall Space Flight Center (MSFC) are able to create maps of the extent of water due to the effects of Hurricane Michael. The synthetic aperture radar (SAR) aboard Sentinel-1B allows for the detection of water on the surface when clouds are present as well as during the night time hours. This product shows three areas: known reference water (blue), anomalous...

Sentinel-1 RGB Imagery from Hurricane Michael
The Alaska Satellite Facility has developed a false color Red, Green, Blue (RGB) composite image of the Sentinel 1A/B Synthetic Aperture Radar (SAR) instrument which assigns the co- and cross-polarization information to a channel in the RGB composite. When used to support a flooding event, areas in blue denotes water present at the time of the satellite overpass prior to the landfall of Hurricane Michael. This product shows three areas: known reference water (...
