Abstract :
This is an overview in the recent progress in the development and implementation of an automated satellite rainfall estimation technique for the Amazonia region. The main research purpose is to provide free of cost satellite rainfall estimates to the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) researchers and other Internet users. The estimates are derived from the GOES-8 geosynchronous satellite infrared (IR) images plus model-derived precipitable water and relative humidity. The technique generates precipitation maps every half-hour over the whole South America region, acknowledges the diurnal variation of precipitation and has better temporal and spatial coverage than the TRMM and DMSP(SSM/1) satellite estimates. The real time rainfall estimates are available in GIF and GRADS format through the NOAA web site http://orbit-net.nesdis.noaa.gov/arad/ht/ff/gilberto.html
