Regional Climate Forcing Data Explorer


All figures shown in this tab are based on the Observation-based climate related forcing (obsclim) outputs from the GFDL-MOM6-COBALT2 model. These data were originally obtained from the ISIMIP Data Repository.

The Climatological map tab below shows the mean climatology (1961-2010) for the environmental variable and within the boundaries of the regional model of interest selected on the left.

The Time series plot tab below shows the area-weighted monthly mean between 1961 and 2010.

Note: The variable names and units shown in the dropdown list and plots come from the GFDL-MOM6-COBALT2 model. We have chosen not apply any transformation to the original model outputs. Instead, we summarised data so we could create the map and time series plots within the limits of all FishMIP regional models. If your model requires environmental data to be in a unit or grid that is different to the one available in the GFDL-MOM6-COBALT2 model, you can download the data from this website and post-process it to meet your needs.




Figures shown in this tab use data from the World Ocean Atlas 2023 (WOA23) . We used the objectively analysed climatologies field to create the climatological maps and area-weighted monthly climatology time series plot. While, the number of observations variable was used to create the maps shown in the sub-tab under the same name.

Note: The variable names and units shown in the dropdown list and plots come from the WOA23. We have chosen not apply any transformation to the original data. Instead, we summarised data so we could create maps and time series plots within the limits of all FishMIP regional models. If your model requires environmental data to be in a unit or grid that is different to the one available in the WOA23a you can download the data from this website and post-process it to meet your needs.

For some regions, the WOA23 dataset may have a very limited number of observations and so it may not offer the most realistic representation of your area of interest. In this case, you may choose to use a different observational product to assess the performance of GFDL-MOM6-COBALT2 outputs. We have an example notebook showing how you can regrid this data to match the grid used by the GFDL-MOM6-COBALT2 model.







Note: The grey ribbon in the plot above shows the spatial variance in the variable of interest.




The following processing steps were taken before comparing GFDL model outputs and WOA data:
1. Climatological mean was calculated using GFDL outputs between 1981 and 2010.
2. WOA data was regridded to match the GFDL outputs.
3. Difference was calculated by substracting WOA data from GFDL model outputs.

This means that positive values in the maps identify areas where GFDL overestimated mean conditions.




The fishing effort and catch data used to create plots in this tab were obtained from 'ISIMIP3a reconstructed fishing activity data (v1.0)' (Novaglio et al. 2024).

The fishing effort and catch data start in 1950, but the fishing effort forcing was reconstructed starting in 1841, which is available for download on the left panel.


About this website

This tool allows regional modellers to visualise environmental data from GFDL-MOM6-COBALT2 and from observations to determine if bias correction (Step 3 below) needs to be applied to the data prior to its use as forcings of a regional marine ecosystem model.



Who is FishMIP?

The Fisheries and Marine Ecosystem Model Intercomparison Project (FishMIP) is an network of more than 100 marine ecosystem modellers and researchers from around the world. Our goal is to bring together our collective understanding to help better project the long-term impacts of climate change on fisheries and marine ecosystems, and to use our findings to help inform policy. You can find more information about FishMIP on our website.



How should I use this tool?

This site has three main tabs:

1. GFDL model outputs

2. World Ocean Atlas 2023 data

3. Model outputs against observations

You can download data that has been subsetted for the regional model of your interest in the first two tabs. Note that all WOA 2023 data are available for download as csv files. GFDL outputs that do not have a depth component (i.e., surface or bottom data) are also available as csv files.

However, due to the size of GFDL outputs with a depth component (e.g. temperature of the water column), these data are only available for download as zip (i.e., compressed) folders containing Zarr files to speed up download times. A Zarr file is a cloud optimised gridded data file format similar to netcdf files. If you use Python, we recommend you use the xarray library to open these files. If you use R, we recommend the Rarrr library. For instructions on how to load these files in R, refer to this example.


How should I cite data from this site?

You can download the data used to create the plots shown in this interactive tool using the 'Download' button included under each tab. As a condition of this tool to access data, you must cite its use. Please use the following citations:

- Fierro-Arcos, D., Blanchard, J. L., Clawson, G., Flynn, C., Ortega Cisneros, K., Reimer, T. (2024). FishMIP input explorer for regional ecosystem modellers.

When using the data products in a publication, please include the following citation in addition to the data product citation provided above:

If using WOA23 data, please refer to their product documentation for the most appropriate citation.

The fishing and catch data should be cited as follows:
