To support the Sentinel-3 mission cal/val, a dedicated remote platform (GSES — Ground Segment Engineering Services) has been implemented. Users can remotely connect to analyse the data from all Sentinel-3A instruments (SLSTR, OLCI and SRAL).
During a nine-month span, we designed a framework on this platform to enable the Cal/Val activities. The work was mainly focused on the SLSTR instrument, but the framework was prepared as a multi-sensor and multi-mission framework from its inception. It addresses, through different open-source off-the-shelf tools, issues such as:
Jean-François is a research engineer at Ifremer (Institut français de recherche pour l'exploitation de la mer), the primary French marine institute. He is currently coordinating the CERSAT, the satellite data centre of Ifremer, managing and producing remote sensing observation products for the oceanographic community.
He is involved in many national and international projects dealing with ocean products development or validation, with EUMETSAT (Ocean & Sea-Ice SAF), ESA (Medspiration, GlobWave, GlobCurrent, OceanFlux, Felyx), CNES (SMOS, CFOSAT), or EU (CMEMS). In particular, for all these projects, he has designed several advanced tools for the search, extraction, and visualisation of remote sensing or in situ data, the implementation of multi-sensor intercomparison/colocation frameworks or the production of matchup databases, with a later interest in thematic Earth Observation data exploitation platforms making use of cloud computing and big data technologies.
Jean-François is also a member of the GHRSST (Group for High Resolution Sea Surface Temperature) science team. He was a visiting scientist at EUMETSAT’s Remote Sensing Product division, supporting the calibration/validation of the Sentinel-3A mission, with a main focus on SLSTR instrument.
