Copernicus Global Ocean Bio-Geo-Chemical Forecast - CAR

  • This dataset provides a 10-day global ocean biogeochemical forecast updated weekly, with daily and monthly mean files.

  • The data includes parameters such as chlorophyll, pH, dissolved oxygen, and dissolved inorganic carbon across 50 vertical levels.

  • The dataset has a spatial resolution of 1/4 degree and covers depths from approximately 0.5m to 5728m.

  • Data is available from January 1, 2022, to September 19, 2025, provided by Copernicus.

  • Users must acknowledge the Copernicus Marine Service when using this free data.

Description

The Operational Mercator Ocean biogeochemical global ocean analysis and forecast system at 1/4 degree is providing 10 days of 3D global ocean forecasts updated weekly. The time series is aggregated in time, in order to reach a two full year's time series sliding window. This product includes daily and monthly mean files of biogeochemical parameters (chlorophyll, nitrate, phosphate, silicate, dissolved oxygen, dissolved iron, primary production, phytoplankton, zooplankton, PH, and surface partial pressure of carbon dioxide) over the global ocean. The global ocean output files are displayed with a 1/4 degree horizontal resolution with regular longitude/latitude equirectangular projection. These products are provided on 50 vertical levels with depths ranging from 0.49m to 5727.92m.

This dataset consists of pH and dissolved inorganic carbon.
