  13. The 2003 NASA Software of the Year The SeaWiFS Data Analysis System by Gene Carl Feldman, Charles McClain, GSFC, Karen Baith, consultant, Mark Reubens, Xiao-Long Wang, Gary Fu, Bryan Franz, SAIC "The SeaWiFS Data Analysis System (SeaDAS) maximizes NASA's investment in Earth remote sensing, delivering data to the user community in a timely manner with the tools to consistently and accurately manipulate the data. SeaDAS provides data display, processing, and analysis support. SeaDAS was designed to identically reproduce all the standard products, including levels 1, 2, and 3 (raw telemetry counts to level 3 global mapped geophysical products), generated by the SeaWiFS Project Office (SPO), while providing users, through open source development, the flexibility of customized processing by adjusting processing parameters or selecting alternative processing methods. SeaDAS is in use at over 500 sites in over 50 nations."
