Within the EUMETSAT program EPS-SG, CNES is responsible of purchasing the IASI-NG system, consisting in three instruments on-board of METOP-SG satellites, the L1C products processors, the Mission Performances Expertise Centre and all the simulators needed for these developments.

IASI-NG mission will produce data for the meteorological, atmospheric chemistry and climatology user's community. L1C products are the first level of products that will be distributed to end-users.

IASI-NG space segment transmits the measurements to ground where they are organized in raw L0 products. L0 products are the main input of the L1C processor that calibrates the spectra and images radiometrically and spectrally, and enriches these data with geolocation and additional information for further spectra exploitation.

CNES has developed several L1C processors in order to generate this L1C product:

  • L1CPOP (L1C Product Operation Processor) for the global and regional mission, that will be integrated in EUMETSAT PDAP (Payload Data Acquisition and Processing) Ground Segment to support the routine phase
  • L1CLOP (L1C Local Operation Processor) for the local mission, that will be integrated in SAF (Satellite Application Facilities) ground stations
  • L1CTOP (L1C Temporary Operational Processor) extending the L1CLOP to the global mission, that will be integrated in the EUMETSAT T-GPS (Temporary Ground Processing System) Ground segment to support the commissioning of METOP-SGA-1 satellite.

This presentation:

  • Présentation de la mission IASI-NG et présentation des produits L1C qui seront distribués par EUMETSAT aux utilisateurs finaux
  • présente les traitements et algorithmes de base de L1C et leur processus de vérification basé sur l’utilisation des outils de simulation du CNES et des données IASI-NG réelles issues d’essais d’instruments
  • L’intégration du traitement L1C dans L1CPOP dans l’infrastructure PDAP complexe basée sur une solution Big Data in-memory
  • L’intégration des traitements L1C dans L1CLOP et L1CTOP dans l’infrastructure simplifiée basée sur une solution d’échange de fichiers.
