  1. BOUSSOLE David ANTOINE CNRS-LOV, France now at: Curtin University, WA, Australia

  2. Description of the team and its expertise

  3. BOUSSOLE: strategy Combination of 3 elements : - A deep-sea mooring, collecting data in a continuous mode Monthly cruises for mooring servicing and acquisition of complementary data - An AERONET coastal station, providing information on the aerosols, which are an important element in the vicarious calibration

  4. Buoy data

  5. Cruises data

  6. 2011 & 2012, nearly full time acquisition

  7. Quantitative summaryat the end of 2012 (over ~11 years) • ~350days at sea since July 2001 (130 cruises aboard the Tethys-II) • ~50 days at sea for buoy deployments / recoveries • ~80 days at sea for on-demand maintenance operations (cleaning, repairs etc..)

  8. MERIS vicarious calibration (3rd reprocessing) Merging BOUSSOLE and MOBY1 data 1: MOBY is an optical buoy near Hawaii, maintained by NASA/NOAA

  9. Matchup results after vicarious calibration

  10. Summary of the methodology • Methods and tools applied See Antoine et al. (2006) (NASA/TM–2006–214147), Antoine et al. 2008 (JGR) • Reporting of protocols (e.g. reporting of field instrument calibration, field measurement protocols and uncertainties, field data processing, matchup and inter-comparison protocols) BOUSSOLE maintains (tries to at least..) a series of technical documents • Reporting of results (e.g. schedule for result reporting; form of results: statistics, plots, technical notes) Yearly in phase E2. Unclear for commissioning phase • Provision of data (e.g. sharing of data with the Sentinel-3 Project, sharing of data with S3VT) BOUSSOLE data are public and available on request Buoy data collected on site every month, then processed and Qced Might need to coordinate with S3 launch, so that a buoy rotation occurs as close as possible before launch

  11. Data requirements • Data Level: Level 1 & 2 • List of products and parameters or algorithms: all reflectances, Chl, Kd, IOPs, TSM, PAR, AOT (essentially all parameters) • Spatial resolution: FR • Data coverage: BOUSSOLE site • Timeline: mission lifetime and beyond • No need for special acquisitions • No need for satellite overpass prediction • No requirements for data timeliness

  12. Thank you
