Entrée dans l'ère BGC-Argo : améliorations du système opérationnel biogéochimique de la mer Méditerranée

International audienceBiogeochemical Argo floats (BGC-Argo) provide an unprecedented availability of high-resolution biogeochemical and optical vertical profiles at near real time. The integration of biogeochemical and optical observations with marine ecosystem models allows to improve the model capability to describe marine ecosystem dynamics at different spatial and temporal scales, also resulting in an increase of the model skill. Recent advancements and future upgrades of the Copernicus Marine Service (CMS) Mediterranean Sea biogeochemical modelling system include the use of BGC-Argo data for validation and assimilation of both biogeochemical and optical components. The focus of this work is to present the upgrade of the BGC-Argo data stream quality check for the CMS Mediterranean Sea biogeochemical modelling system workflow and to discuss a novel skill assessment framework oriented to evaluate key biogeochemical processes and ecosystem dynamics (e.g. deep chlorophyll maximum depth, nitracline depth, minimum oxygen depth) and optical characteristics (bbp700 converted data) that benefit from the particularly rich and high quality level of the BGC-Argo network in this semi-enclosed sea
