Baltic Sea Multiyear Ocean Colour Plankton, Reflectances and Transparency L3 daily observations

Phytoplankton biomass and diversity Ocean colour

'''Short description:'''

For the '''Baltic 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 neural network (Brando et al. 2021) 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)
'''''pp''''' with the Integrated Primary Production (PP).

'''Upstreams''': SeaWiFS, MODIS, MERIS, VIIRS, OLCI-S3A (ESA OC-CCIv6) for the '''""multi""''' products, and OLCI-S3A & S3B for the '''""olci""''' products

'''Temporal resolution''': daily

'''Spatial resolution''': 1 km for '''""multi""''' (4 km for '''""pp""''') and 300 meters for '''""olci""'''

To find this product in the catalogue, use the search keyword '''""OCEANCOLOUR_BAL_BGC_L3_MY""'''.
