For the **Mediterranean 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 algorithms (Case 1 waters: Volpe et al., 2019, with new coefficients; Case 2 waters, Berthon and Zibordi, 2004) and Phytoplankton Functional Types (PFT) evaluated via region-specific algorithm (Di Cicco et al. 2017)
* **_reflectance**_ with the spectral Remote Sensing Reflectance (RRS)
* **_transparency**_ with the diffuse attenuation coefficient of light at 490 nm (KD490) (for **""multi**"" observations achieved via region-specific algorithm, Volpe et al., 2019)
* **_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 resolutions**: 1 km for **""multi""** and 300 meters for **""olci""**

To find this product in the catalogue, use the search keyword **""OCEANCOLOUR_MED_BGC_L3_NRT""**.
