Load->SeaWiFS L0 Load SeaWiFS Level-0 (HRPT) files.
Load-> MODIS Ocean Data Load MODIS Ocean L1A, L1B, L2, L2A, L2B, L2 SST, L3 & L4 files.
Load-> OCTS(NASDA format) Load NASDA OCTS L1B, L2 and L3 mapped files.
Load-> OCTS(SeaDAS format) Load SeaDAS OCTS L2 files.
Load-> CZCS/SeaDAS HDF Load SeaDAS CZCS L1A and L2 files.
Load-> CZCS/DAAC HDF & PST Load Goddard DAAC HDF CZCS files. Level-2 and Level-2 browse file types.
