⚠️ Breaking Changes

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

  As a result of an issue being found (#400),
  models that rely on exogenous ozone forcing are now required to use different versions of the ozone files
  for pre-industrial control (and related) simulations and historical (and related) simulations.
  For all historical (and related) simulations, files with the source ID FZJ-CMIP-ozone-2-0 should be used.
  For pre-industrial control (and related) simulations, files with the source ID FZJ-CMIP-ozone-1-2 should be used
  (note that this guidance differs from the email communication sent by the CMIP IPO on 12 February 2026).
  For details of your options for pre-industrial control simulations,
  please see the ozone dataset page.

  The CMIP Panel co-chairs are recommending that,
  for modelling centres who rely on ozone as an external forcing,
  historical, and other relevant DECK (e.g., AMIP), simulations
  should be re-run with the FZJ-CMIP-ozone-2-0 ozone if possible.
  (Pre-industrial control simulations do not need to be re-run
  because they are unaffected by the release of FZJ-CMIP-ozone-2-0.)

  If any modelling centres cannot re-run their historical simulations,
  they should contact the ozone forcing providers for guidance on
  how to ensure a smooth connection between the scenario ozone forcing files.

  If any modelling centres run historical simulations
  with both the FZJ-CMIP-ozone-1-2 and FZJ-CMIP-ozone-2-0 forcing,
  these simulations would be of interest to the Forcings Task Team. (#413)

v6.7.19

Announcements

• 🚨 Updated future volcanic emissions files (UOEXETER-ScenarioMIP-2-2-2) have been released. The previous files (UOEXETER-ScenarioMIP-2-2-1) had an incorrect mask applied, so did not end up with the same state as the pre-industrial control files. If you started scenario simulations with UOEXETER-ScenarioMIP-2-2-1, please restart and use UOEXETER-ScenarioMIP-2-2-2 instead
• Emissions are now available for two of the ScenarioMIP scenario experiments. For models with interactive chemistry, all forcings required for simulations should now have been released

Changelog

🆕 Features

• Added future emissions for the high (h) and very low (vl) scenarios (#402)

🐛 Bug Fixes

• Added fixed future volcanic emissions files (UOEXETER-ScenarioMIP-2-2-2). The previous files (UOEXETER-ScenarioMIP-2-2-1) had an incorrect mask applied, so did not end up with the same state as the pre-industrial control files. (#402)
