Changelog

v2.7.1

Highlights

This is a bugfix release where we unpin cf-units to allow the latest iris=3.4.0 to be installed. It also includes an update to the default configuration used when searching the ESGF for files, to account for a recent change of the CEDA ESGF index node hostname. The changelog contains only changes that were made to the main branch.

v2.7.0

Highlights

• We have a new preprocessor function called ‘rolling_window_statistics’ implemented by Liza Malinina

Highlights

• The new preprocessor extract_location() can extract arbitrary locations on the Earth using the geopy package that connects to OpenStreetMap. For details, see Extract location.

• Time ranges can now be extracted using the ISO 8601 format. In addition, wildcards are allowed, which makes the time selection much more flexible. For details, see Recipe section: Datasets.

• The new preprocessor ensemble_statistics() can calculate arbitrary statitics over all ensemble members of a simulation. In addition, the preprocessor multi_model_statistics() now accepts the keyword groupy, which allows the calculation of multi-model statistics over arbitrary multi-model ensembles. For details, see Ensemble statistics and Multi-model statistics.

This release includes

Backwards incompatible changes

• Update Cordex section in config-developer.yml (#1303) francesco-cmcc. This changes the naming convention of ESMValCore’s output files from CORDEX dataset. This only affects recipes that use CORDEX data. Most likely, no changes in diagnostics are necessary; however, if code relies on the specific naming convention of files, it might need to be adapted.

• Dropped Python 3.7 (#1530) Manuel Schlund. ESMValCore v2.5.0 dropped support for Python 3.7. From now on Python >=3.8 is required to install ESMValCore. The main reason for this is that conda-forge dropped support for Python 3.7 for OSX and arm64 (more details are given here).

v2.2.0

Highlights

ESMValCore is now using the recently released Iris 3. We acknowledge that this change may impact your work, as Iris 3 introduces several changes that are not backward-compatible, but we think that moving forward is the best decision for the tool in the long term.

This release is also the first one including support for downloading CMIP6 data using Synda and we have also started supporting Python 3.9. Give it a try!
