Software that allows remote users to browse satellite-derived images and in-situ data archives of interest to oceanographers via Internet has been developed by researchers at the University of Rhode Island/s Graduate School of Oceanography. The tool, called “Xbrowse,” can access a recently assembled archive of Advanced Very High Resolution Radiometer (AVHRR) Sea Surface Temperature (SST) imagery covering the Western Atlantic from 1979 to present, with new passes being added daily. From January 1979 through March 1982, the coverage is spotty. From April 1982 to present, every pass downloaded on the Wallops Island receiving station is available. Each pass in the archive has been remapped to standard geophysical coordinates.
