v6.7.41

Announcements

• Breaking change: Updated versions of the emissions forcing for the vl and h ScenarioMIP scenarios have been released (see source IDs IIASA-IAMC-vl-1-1-1 and IIASA-IAMC-h-1-1-1). This update fixes an issue with the biomass burning emissions (which are all zero in IIASA-IAMC-vl-1-1-0 and IIASA-IAMC-h-1-1-0). If you do not use biomass burning emissions, you do not need to re-run. Otherwise, please re-run to use the correct values.
• Emissions (both anthropogenic and biomass burning) forcing for all ScenarioMIP scenarios is now available (see source IDs of the form IIASA-IAMC-*-1-1-1)

v6.7.35

Announcements

• Greenhouse gas concentration forcing for all ScenarioMIP scenarios and their extensions is now available, see https://input4mips-cvs.readthedocs.io/en/latest/dataset-overviews/greenhouse-gas-concentrations/ and https://metagrid.esgf-west.org/search?project=input4MIPs&activeFacets=%7B%22mip_era%22%3A%22CMIP7%22%2C%22institution_id%22%3A%22CR%22%2C%22source_version%22%3A%221.1.0%22%7D

Changelog

🆕 Features

• Added greenhouse gas concentration forcing for all ScenarioMIP scenarios and their extensions (see source IDs of the form CR-*-1-1-0). This includes updates of the already released vl and h scenario forcings, but these updates are small so if you have already run with the v1.0.0 versions of these forcings for the vl or h simulations, you do not need to re-run.

v6.7.32

Announcements

• There is an update to the nitrogen deposition data (new data is published under source ID FZJ-CMIP-nitrogen-2-0). However, if you already have simulations that use the previous version (source ID FZJ-CMIP-nitrogen-1-2`), you do not need to re-run. Further details below and at https://input4mips-cvs.readthedocs.io/en/latest/dataset-overviews/nitrogen-deposition/

Changelog

⚠️ Breaking Changes

• Added data with the source ID FZJ-CMIP-nitrogen-2-0. This data updates the historical forcing data provided in FZJ-CMIP-nitrogen-1-2.

  As a result of an issue being found (#425),
  a new version of the nitrogen deposition forcing has been released.

  Modelling centres who have already run their piControl and/or historical simulations do not need to re-run.
  Modelling centres who have not yet started their piControl and/or historical simulations should use the FZJ-CMIP-nitrogen-2-0 data.
  For further details about the error and recommended action,
  please see the nitrogen deposition dataset page.

  If any modelling centres run piControl and/or historical simulations with both the FZJ-CMIP-nitrogen-2-0 and FZJ-CMIP-nitrogen-1-2 forcing,
  these simulations would be of interest to the Forcings Task Team. (#427)
