Rank 42 documents Oceansat-2 — ISRO's dedicated ocean observation satellite that tracks ocean color, chlorophyll concentrations, and sea surface winds across the Indian Ocean region for marine research, fisheries management, and weather modelling. Launched 23 September 2009 aboard PSLV from Sriharikota, the compact Earth observation bus carries an ocean color monitor and scatterometer payload pairing visible-band water analysis with microwave wind measurement — dual instruments that earlier single-purpose missions could not combine. The mission supports India's coastal economy and cyclone track forecasting by supplying daily ocean state data to research institutions and operational meteorology centres. Wallimilist renders the profile-monument bus with sensor scan beam, Indian Ocean wave geometry, cream horizontal-band archive with OCEANSAT 2 slab title, OCEAN MONITORING SATELLITE kicker, and TRACKS OCEAN COLOR AND SURFACE WINDS footer exactly as the master PNG dictates — ISRO and PSLV emblems, specimen data bands, and curator copy on Indian marine observation heritage.
