The piControl forcing should come from files with the source ID `FZJ-CMIP-ozone-1-2` data,
(there are no specific piControl files available in the `FZJ-CMIP-ozone-2-0` data).
Note that this guidance differs from the email communication sent by the CMIP IPO on 12 February 2026.
The CMIP IPO sent this guidance in their
[email communication on 16 February 2026](../forcings-email-archive/2026-02-16/#recommendation-for-pre-industrial-control),

This may be useful for those wishing to post-process the ozone forcings into other forms

Three state-of-the-art stratosphere-troposphere-resolving chemistry-climate models
- WACCM-CESM (USA), CMAM (Canada), and EMAC (Germany) -
have been used to create this dataset.
The models were run in amip (or coupled?) mode driven by the DECK CMIP7 forcing datasets.
More details on the simulations and their fidelity against observations
will be documented in a peer-reviewed journal article (Hegglin et al, in prep).

## Differences in format from CMIP6 or other previous versions

The data format is currently very similar, if not the same as CMIP6
