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) 

**Upstreams**: SeaWiFS, MODIS, MERIS, VIIRS, OLCI-S3A (ESA OC-CCIv5) 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_BAL_BGC_L3_MY""**.
