1. Center for Satellite Applications and Research (STAR) Review 09 – 11 March 2010 NOAA CoastWatch/OceanWatch Ocean Color Activities: Contributions to Ocean Color Radiometry-Virtual Constellation S. Ramachandran 2, K. Hughes 1 (PRINCIPAL GOVERNMENT INVESTIGATOR), Y.S. Kim 3, M. Wang 1 1 NOAA/NESDIS/STAR, 2 SP-Systems Inc, 3 DELL/Perot Systems Government Services Requirement: Develop observational systems to support integrated ecosystem assessments, regional management, and climate science. Science: How can observing system and NOAA operational products be improved to better analyze ocean, land, and climate processes. Benefit: Collaborative ocean color radiometry from space will mitigate potential gaps in missions / operations / capabilities. Science Challenges: Differences in calibration procedures and sensor band differences make inter-sensor derived product comparisons difficult. Also required will be acquisition station coordination and support, processing system development and operations and calibration/validation. Next Steps: Investigate acquisition station capability and availability; Explore satellite differences, optimum product suite development, and establish and sustain Cal/Val activities. Product improvement will involve SWIR atmospheric correction as well as the Global Forecast System (GFS) ancillary data from NCEP instead of monthly climatology data for Ocean Color data processing. Transition Path: Transition from operations in US coastal waters (CoastWatch) to global science quality (OceanWatch). SensorsSystems Cal/Val Coverage NOAA CoastWatch/OceanWatch supports the Ocean Color Radiometry-Virtual Constellation (OCR-VC). The OCR-VC will provides a long time series of calibrated OCR from multiple satellites with activities including Cal/Val, merging of satellite data and in situ data, product generation as well as demonstration of new improved applications. Application Demonstrations HABs : Ocean Color data are routinely used to monitor the location and movement of harmful algal blooms (HABs) using Chlorophyll concentration anomalies. WQ: Monitor water quality (WQ) in the Chesapeake Bay using derived products such as total suspended matter (TSM) to measure sediment and contaminant loading from terrestrial runoff. LM: Support for ecological forecasts, stock assessments and living marine (LM) resource management. 1)MODIS, SeaWiFS, MERIS, OCM-2 (2009+) 2) VIIRS-NPP, OLCI (2010+) 3) S-GLI, VIIRS-NPOESS (2014+) 1km daily (current) Planned N.
