The GRIP GOES 13 Overshooting Top dataset was produced during the GRIP Field Experiment for use with the Real Time Mission Monitor (RTMM) tool. The major goal was to better understand how tropical storms form and develop into major hurricanes. The magnitude of each overshooting top is the difference between the 'anvil' temperature and the 'overshooting top' temperature. These magnitudess are represented as a color coded display using Google Earth, a virtual globe, map and geographical information program.
