Multispectral Image Enhancement Reveals Kuwaiti Oil Plumes
Abstract
Absorbing of incoming solar radiation at visible wavelengths, oil smoke is nearly invisible over water on many environmental satellite images. To improve the detectability of smoke, the authors construct bispectral composites from images from the NOAA Advanced Very High Resolution Radiometer (AVHRR). These composites are constructed from a ratio between AVHRR channels 1 and 2. While neither channel by itself shows smoke overwater, the ratio image often depicts smoke quite distinctly. The authors discuss an interactive program on a computer workstation which enables even an untrained user to develop further enhancements using this ratio image....
