Two cloud-free high resolution remotely sensed images of flooding in the US Midwest have been made available for anonymous FTP on climate.gsfc.nasa.gov (128.183.46.16) in directory pub/gumley. The images are stored in GIF and JPEG format. The images were acquired on July 29, 1993 by the MODIS Airborne Simulator (MAS), a scanning visible/near-infrared/infrared spectrometer that flies on a NASA ER-2 aircraft. The direction of flight is from right to left. Nadir is along a line across the center of the image. The images have been resampled so that the spacing between the center of each pixel is 64 meters in the along track and cross track directions. In each image the vertical distance shown is 37 kilometers. The image of St. Louis is 64 kilometers wide. The image of Kansas City is 46 kilometers wide. Both images are oriented approximately East-West. The images were prepared by Liam Gumley (Climate and Radiation Branch) and Michael King (Earth Sciences Directorate), NASA Goddard Space Flight Center. The NASA ER-2 is provided by NASA Ames Research Center. Please direct any correspondence to gumley@climate.gsfc.nasa.gov
