'''Short description:'''

For the '''Baltic Sea''' Ocean '''Satellite Observations''', the Italian National Research Council (CNR – Rome, Italy), is providing '''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)
'''''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''': OLCI-S3A & S3B

'''Temporal resolution''': daily

'''Spatial resolution''': 300 meters
