Presentation Transcript

  1. IOCCG Task Force on Satellite Sensor Calibration Ewa Kwiatkowska (EUMETSAT) Gerhard Meister (NASA) IOCCG#24, 4-6 April 2019, University of Science Technology, Hanoi, Vietnam

  2. Motivation for the sensor calibration task force Recommendation from the INSITU-OCR White Paper OCR-VC – aims to “provide long time series of calibrated ocean colour radiance at key wavelength bands from measurements obtained from multiple satellites.  OCR-VC activities will include calibration, validation, merging of satellite and in situ data, product generation, as well as development and demonstrations of new and improved applications.” Mission Statement • Create a framework for active and hands-on collaboration among instrument calibration and characterization experts from the Agencies engaged in the OCR-VC initiative. • The collaboration focuses on calibration needs specific to ocean-color measurements and has the objective to maximize the accuracy and temporal and spatial stability of OCR records from individual missions for the purpose of climate, research and operational applications. 2 IOCCG#24, 4-6 April 2019, University of Science Technology, Hanoi, Vietnam

  3. Meetings and collaborations • Biennial IOCS meetings • Side-meetings (e.g. S3VT) • Inter-agency collaborations (e.g. visiting scientists) • Breakout workshop at IOCS’19 is very strongly supported IOCCG#24, 4-6 April 2019, University of Science Technology, Hanoi, Vietnam

  4. Measureable benefits of task force collaborations • “the best way to get an overview of the calibration status and approaches for all ocean color missions” • Sentinel-3 OLCI in-flight diffuser characterization • Strategy and requirements for the PACE OCI Solar Calibration • Improved prelaunch calibration approaches via shared experience from similar sensors • Lunar calibration, community lunar model: GSICS implementation of the ROLO (GIRO) IOCCG#24, 4-6 April 2019, University of Science Technology, Hanoi, Vietnam
