Date of Images:<\/SPAN><\/P> 9/29/2022<\/SPAN><\/P> Date of Next Image:<\/SPAN><\/P> None Expected<\/SPAN><\/P> Summary:<\/SPAN><\/P> Scientists at NASA's Marshall Space Flight Center created these water extents on September 29, 2022 using the RADARSAT-2 Synthetic Aperture Radar (SAR) instrument. These images can be used to see where water is located at the time of the satellite overpass. This product shows all water detected and differentiates between normal water areas and some flooded areas. It's important to note that all flooded areas may not be captured by these images. To determine where additional flooding may have occurred, combine this layer with other data sets.<\/SPAN><\/P> This service contains modified RADARSAT-2 data, collected through Hazards Data Distribution System (HDDS)-USGS; post-processing and data product development performed by NASA Marshall Space Flight Center.
