Global Ocean Colour: Bio-Geo-Chemical, L4, from Satellite Observations, Primary Production, Multi-Sensor 4KM

  • The Global Ocean Colour dataset provides Bio-Geo-Chemical oceanographic variables derived from multiple satellites.

  • This dataset offers a global estimate of marine primary production, expressed in mg/m²/day.

  • The dataset includes bands for Primary Production (PP), PP uncertainty, and a land/water mask.

  • The data is available monthly from April 2023 to September 2025.

  • This dataset is released under a Service Level Agreement by the E.U. Copernicus Marine Environment Monitoring Service.

Description

The Global Ocean Colour (Copernicus-GlobColour) dataset is a Bio-Geo-Chemical (BGC) product developed by ACRI-ST. Derived from multiple satellite sources like SeaWiFS, MODIS, and OLCI. It provides a comprehensive range of oceanographic variables, including: Chlorophyll (CHL), Phytoplankton Functional types and sizes (PFT), Primary Production (PP), Suspended Matter (SPM), Secchi Transparency Depth (ZSD), Diffuse Attenuation (KD490), Particulate Backscattering (BBP), Absorption Coefficient (CDM), Reflectance (RRS) and more.

This dataset provides a global estimate of marine primary production. It uses multi-sensor satellite data to measure the rate of carbon fixation by phytoplankton, which is a key indicator of ocean health. The primary production values are expressed in units of mg/m^2/day, making it a valuable tool for monitoring global carbon cycles and marine ecosystem dynamics.

Documentation:

NOTE: The provider may remove Copernicus Marine data (especially Near Real-Time, NRT, observations) from their repository after some time, possibly aggregating that data into different (e.g., monthly) products. However, the corresponding assets remain available in the Earth Engine collection.
