'''Short description:'''For the '''Black Sea''' Ocean '''Satellite Observations''', the Italian National Research Council (CNR – Rome, Italy), is providing multi-years '''Bio-Geo_Chemical (BGC)''' regional datasets:* '''''plankton''''' with the phytoplankton chlorophyll concentration (CHL) evaluated via region-specific algorithms (Zibordi et al., 2015; Kajiyama et al., 2018) and Phytoplankton Functional Types (PFT) evaluated via region-specific algorithm * '''''reflectance''''' with the spectral Remote Sensing Reflectance (RRS)* '''''transparency''''' with the diffuse attenuation coefficient of light at 490 nm (KD490) * '''''optics''''' including the IOPs (Inherent Optical Properties) such as absorption and scattering and particulate and dissolved matter (ADG, APH, BBP), via QAAv6 model (Lee et al., 2002 and updates)'''Upstreams''': SeaWiFS, MODIS, MERIS, VIIRS-SNPP & JPSS1, OLCI-S3A & S3B for the '''"multi"''' products, and OLCI-S3A & S3B for the '''"olci"''' products'''Temporal resolution''': daily'''Spatial resolution''': 1 km for '''"multi"''' and 300 meters for '''"olci"'''To find this product in the catalogue, use the search keyword '''"OCEANCOLOUR_BLK_BGC_L3_MY"'''.'''DOI (product) :''' https://doi.org/10.48670/moi-00303
