1 NASA SIMBIOS Experience International Collaboration OCRT Meeting 24 April 2012 Bryan Franz and the NASA Ocean Biology Processing Group

2 OCEAN COLOR MISSIONS view in late 1990's 12/10/01 Instrument (Mission; Country)969798990001020304050607080910 Global OCTS (ADEOS-I; Japan) POLDER (ADEOS-I/II; France & Japan) SeaWiFS (Orbview-2; U.S.) MODIS (Terra; U.S.) MISR (Terra; U.S. ) MERIS (ENVISAT; ESA) GLI (ADEOS-II; Japan) MODIS (Aqua; U.S.) VIIRS (NPP: U.S.) Limited Coverage MOS (Priroda; Germany & Russia) MOS (IRS; Germany & India) OCI (ROCSAT; Taiwan) OCM (IRS-P4; India) OSMI (KOMPSAT; South Korea)

3 Sensor Intercomparison & Merger for Biological & Interdisciplinary Ocean Studies NASA funded effort from 1996 – 2003 alternative to EOS Color mission (SeaWiFS follow-on) Goals Ensure development of internally consistent research products and time series from multiple satellite ocean color data sources Develop methodologies for cross-calibration of satellite ocean color sensors Develop methodologies for merging data from multiple ocean color missions Promote cooperation between ocean color Projects & Missions

4 Organizational Structure Distributed Science Team U.S. participants funded through 3-year NRAs 1997-2000: 21 U.S. and 5 international participants 2000-2003: 21 U.S. and 14 international participants Centralized Project Office co-located with SeaWiFS Project ** technical & program management, documentation science team coordination, contract management technical interface with other space agencies: NASDA, CNES, ESA, KARI organizations: NIST, IOCCG, JRC, DLR projects: EOS, AERONET

5 Field Program Collaborations Oceanographic Field Campaigns INDOEX (1999) ACE-Asia (2001) Contracted Field Investigations 1997-2000: 15 US 2000-2003: 11 US + International SeaBASS (2003) 300,000 pigments 13,500 depth profiles 44 institutions 14 countries

8 Satellite Mission Collaborations Data acquisition, processing, and distribution OCTS acquisition at Wallops (NASDA/Japan) MOS acquisition at Wallops (DLR/Germany, ISRO/SAC/India) Instrument calibration, data processing, and algorithms OCTS global GAC (NASDA/Japan), full mission reprocessing OSMI (KARI/Korea) processing software and instrument calibration OCTS-POLDER cross-calibration (NASDA/Japan, CNES/France) MOS-SeaWiFS cross calibration and algorithm development, destriping Instrument/algorithm workshops Japanese-US Working Group on Ocean Color (JUWOC) MOS Ocean Color Meetings (1998-2000)

9 Lasting Impact: NASA's Sensor-Independent Approach Multi-Sensor Level-1 to Level-2 (common algorithms) SeaWiFS L1A MODISA L1B MODIST L1B OCTS L1A MOS L1B OSMI L1A CZCS L1A MERIS L1B OCM-1 L1B OCM-2 L1B VIIRS-L1B sensor-specific tables: Rayleigh, aerosol, etc. Level-2 to Level-3 Level-2 Scene observed radiances ancillary data water-leaving radiances and derived prods Level-3 Global Product vicarious calibration gain factors predicted at-sensor radiances in situ water-leaving radiances (MOBY)

10 Lasting Impact: SeaDAS Multi-Mission Support

11 Lasting Impact: International Community over 18,000 posts and 14.5 million views since 2004

12 What Worked Centralized project office to coordinate activities including budgetary control Satellite Project a full partner in the international effort able to implement new products and algorithms from international team not restricted to mission-specific Science Team input Funded investigators required to submit data to SeaBASS contractual obligations Open Data Policies unrestricted access to satellite data (SeaWIFS, MODIS) unrestricted (delayed) access to in situ data (SEABASS)

13 What Worked Visiting scientists to address specific topics focused activities, exchange ideas, implement, and test algorithms Antoine & Morel (f/Q algorithm evaluation) Tanaka & Fukushima (OCTS & GLI, cal/val & processing) Hagolle & Nicolas (POLDER implementation) Kim (OSMI implementation, cross-calibration) Neumann (IRS-P3/MOS processing stream) Zibordi, Deschamps, Yamamoto, Kopelovich Distributed, open source software common software framework enabling collaboration and sharing Annual meetings working level, focused, technical, & documented
