This directory contains netCDF files for the global ocean marine carbonate system at an 8-daily by 0.25deg resolution.

Versioning

This version is a release version and is no longer in beta. However, that does not mean we wont create another release if we discover something suspicious. Any updates from now on will be consistent with the naming and increase the version number v2023.XX.

Folder structure

The folder structure is ./<variable>/<year>/<single_netcdf_for_each_time_step>.nc. You can see all the variables on the HTTPS server – includes temperature and salinity. The data runs from 1982 to the end of 2022 with 46 time steps for each year. The size for each variable (1982-2022) is between 2.5 and 3.5 GB.

File structure and metadata

Each netCDF contains only one variable. The metadata also has a start and end time as well as min/max lat/lon. The information about the settings used in PyCO2SYS is also included in each file’s metadata.

Evaluation

The folder _EVALUATION contains some plots and CSVs of the comparison with GLODAP2023. - ALK has an open ocean RMSD of 17.98 umol kg-1 and bias of 0.93 umol kg-1. Regionally, also quite good (except for ICE biomes) - DIC has an open ocean RMSD of 17.23 umol kg-1 and bias of 0.06 umol kg-1. Though regionally, suffers a lot more.
