VALIDATION STRATEGIES OF AOP MEASUREMENTS IN SUPPORT OF PACE MISSION

Ocean color satellite missions require a detailed validation process to ensure measurement uncertainty is adequately characterized when validating in situ radiometric measurements with satellite acquisitions. Within the validation strategies for PACE, in situ radiometry workflow has significantly evolved in support the specific requirements of this mission. Our data collection protocol and reporting has been reviewed in accordance with international community guidelines. Data submissions to our ocean color repository SeaBASS follow a detailed quality control and quality assurance process. To support this work, specific software for radiometry processing has been developed to calculate surface products for satellite validation, including uncertainty estimates. Visual SeaBASS is a software that generates validation matchup products from our standing SeaBASS data repository contributed by the community. Visual SeaBASS is an open-source software that implements the most recent radiometric community protocols and provides a standardized processing for in-water radiometry for a variety of sensors and data formats. The data workflow is completed with the generation of a high quality in situ bio-optical database for algorithm development. NOMAD is now also including hyperspectral measurements and uncertainty estimates in support of PACE data requirements. It also includes other non-validation optical scenarios for algorithm development in special conditions. This work presents the development of these new elements which are part of the ongoing PACE validation plan.
