Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 BOUSSOLE David ANTOINE CNRS-LOV, France now at: Curtin University, WA, Australia
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 Description of the team and its expertise
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 BOUSSOLE: strategy Combination of 3 elements : Monthly cruises for mooring servicing and acquisition of complementary data - A deep-sea mooring, collecting data in a continuous mode - An AERONET coastal station, providing information on the aerosols, which are an important element in the vicarious calibration
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 Buoy data
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 Cruises data
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November & 2012, nearly full time acquisition
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 Quantitative summary at the end of 2012 (over ~11 years) ~ 350 days 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..)

Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 MERIS vicarious calibration (3 rd reprocessing) Merging BOUSSOLE and MOBY 1 data 1: MOBY is an optical buoy near Hawaii, maintained by NASA/NOAA
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 Matchup results after vicarious calibration
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 Summary of the methodology Methods and tools applied See Antoine et al. (2006) (NASA/TM–2006–214147), Antoine et al (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
Sentinel-3 Validation Team (S3VT) Meeting ESA/ESRIN, Frascati, Italy, th November 2013 Data requirements Data Level: Level 1 & 2 List of products and parameters or algorithms: all reflectances, Chl, K d, 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
