Description of the team and its expertise


BOUSSOLE: strategyCombination 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


Buoy data


Cruises data


2011 & 2012, nearly full time acquisition


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..)

MERIS vicarious calibration (3rd reprocessing)Merging BOUSSOLE and MOBY1 data

1: MOBY is an optical buoy near Hawaii, maintained by NASA/NOAA


Matchup results after vicarious calibration


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


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
