This image combines observations taken on May 5, 2008, by the Moderate Resolution Imaging Spectroradiometer (MODIS) sensors on NASA’s Terra and Aqua satellites. It uses the cloud-free observations from each to get the clearest possible picture. Even so, cloud cover obscured both satellites’ views in some areas, so additional flooding could be present. This image also incorporates a percent tree cover dataset called the MODIS Vegetation Continuous Fields. Flooded areas are blue, cities are red, and tree cover appears in shades of green (dense tree cover) to pale yellow (sparse tree cover).
