Service Description: Date of Images: 2/1/2019; 2/8/2019; 2/13/2019; 2/14/2019; 2/19/2019; 2/25/2019; 2/26/2019; 3/4/2019 Date of Next Image: Unknown Purpose/Summary: 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 before or after the start of the flooding event. Suggested Usage: In this image, water appears in blue, vegetated areas in shades of green and urban areas in bright orange. It is recommended to use this product with ancillary information to derive flooded areas. Satellite/Sensor: Synthetic Aperture Radar on European Space Agency's (ESA) Copernicus Sentinel-1A/B satellite; 30 m resolution Credits: Sentinel data used in this derived product, contains modified Copernicus Sentinel data (2019), processed by ESA, Alaska Satellite Facility, and NASA Marshall Space Flight Center.
