AB: The ISCCP B1 satellite data is sub-sampled in time and space to 3-hour and 10km resolutions, making it useful in the detection of overshooting convection and its role in upper tropospheric and lower stratospheric (UT/LS) water vapor exchange. The geostationary satellite infrared radiances in the IR window at 11µm and the water vapor absorption band at 6.7µm have been inter-calibrated against channels 8 and 12 of NOAA-17/HIRS and converted to brightness temperatures. Data from these two channels are used to perform an analysis of overshooting cloud tops in the global tropical band between 15N and 15S for the period June 2006 through May 2007 using the Schmetz et. al (1997) approach. The temporal and spatial distribution of overshooting cloud top events will be presented and analyzed in the context of the UT/LS water vapor exchange.
