xscen - v0.12.1

Contributors to this version: Juliette Lavoie (@juliettelavoie), Gabriel Rondeau-Genesse (@RondeauG), Éric Dupuis (@coxipi), Pascal Bourgault (@aulemahal).

New features and enhancements

  • xscen officially supports Python 3.13. (PR/551).

Breaking changes

  • Make strip_cat_metadata False by default in xs.save_to_zarr and xs.save_to_netcdf. (PR/556, GH/555).
  • New official column driving_member. For RCMs, this should store the driver's realisation number, while the member column should now store the RCM simulation's realisation number, noted as "rX". This member should approximately map to the "realization" part of CORDEX-CMIP6's "versionrealization" facet (the version part mapping to the already existing version column). The member restricting feature of ``searchdatacatalogshas been adapted, but continues to work with catalogs missing thedrivingmember`` column. (PR/559).
  • Also adapted from the CORDEX-CMIP6 specifications, the driving_model column does not need to indicate the driver's institution name anymore. (PR/559).
  • For Python 3.13 support, xscen now requires clisops>=0.16.1 and xsdba>=0.4.0. (PR/551).
  • Minimum required intake-esm has been updated to >=2025.2.3. (PR/551).
  • Temporarily pinned numcodecs to <0.16.0 for compatibility with zarr. (PR/571).

Bug fixes

  • Fixed the default for xs.utils.maybe_unstack. (PR/553).
  • Patch xsdba.units.convert_units_to with xclim.core.units.convert_units_to with context="infer" locally in xs.train and xs.adjust instead of using xc.core.settings.context. (PR/552).
  • Fixed a bug in xs.utils.clean_up where attributes would be dropped when using the missing_by_vars argument. (PR/569, GH/568).
  • Allow undetectable frequencies in xs.extract.resample. (PR/567).

Internal changes

  • Added the ability to test xESMF-related functions with tox / pip. (PR/554).
  • Updated the pins for xclim, xarray, dask, and rechunker. (PR/570).
  • More accurate listing of dependencies for the project in pyproject.toml and environment*.yml. (PR/557).
  • sphinx dependencies are more streamlined in the docs environment. (PR/557).
  • Added codespell, deptry, vulture, and yamllint to the linting checks. (PR/557).

Contributors to this version: Juliette Lavoie (@juliettelavoie), Pascal Bourgault (@aulemahal), Gabriel Rondeau-Genesse (@RondeauG), Trevor James Smith (@Zeitsperre).

New features and enhancements

  • The mask argument in stack_drop_nans can now be a list of dimensions. In that case, a dropna(how='all') operation will be used to create the mask on-the-fly. (PR/450).
  • Few changes to clean_up:
    • The convert_calendar function now uses xarray instead of xclim. (PR/450).
    • The attrs_to_remove and remove_all_attrs_except arguments now use real regex. (PR/450).
    • Multiple entries can now be given for change_attr_prefix. (PR/450).
  • minimum_calendar now accepts a list as input. (PR/450).
  • More calendars are now recognized in translate_time_chunk. (PR/450).
  • new_dim in unstack_dates is now None by default and changes depending on the frequency. It becomes month if the data is exactly monthly, and keep the old default of season otherwise. (PR/450).
  • Updated the list of libraries in show_versions to reflect our current environment. (PR/450).
  • New xscen.catutils.patterns_from_schema to generate all possible patterns from a given schema (or one of xscen's default), to use with :py:func:parse_directory. (PR/431).
  • New DataCatalog.copy_files to copy all files of catalog to a new destination, unzipping if needed and returning a new catalog. (PR/431).
  • Convenience functions xs.io.zip_directory and xs.io.unzip_directory (for zarrs). (PR/431).
  • New argument compute_indicators: rechunk_input to rechunk the inputs to resample-appropriate chunks before calling xclim. (PR/431).
  • New xs.indicators.get_indicator_outputs to retrieve what variable name(s) and frequency to expect from an xclim indicator. (PR/431).
  • xscen now supports launches tests from pytest with the --numprocesses option. See the pytest-xdist documentation <https://pytest-xdist.readthedocs.io/en/stable/>_ for more information. (PR/464).
  • Conservative regridding now supports oblique mercator projections. (PR/467).
  • The automatic name for the weight file in regrid_dataset is now more explicit to avoid errors, but now requires cat:id and cat:domain arguments for both the source and target datasets. (PR/467). ### Bug fixes
  • Fixed bug with reusing weights. (GH/411, PR/414).
  • Fixed bug in update_from_ds when "time" is a coordinate, but not a dimension. (:pull: 417).
  • Avoid modification of mutable arguments in search_data_catalogs (PR/413).
  • ensure_correct_time now correctly handles cases where timesteps are missing. (PR/440).
  • If using the argument tile_buffer with a shape method in spatial.subset, the shapefile will now be reprojected to a WGS84 grid before the buffer is applied. (PR/440).
  • maybe_unstack now works if the dimension name is not the default. (PR/450).
  • unstack_fill_nan now works if given a dictionary that contains both dimensions and coordinates. (PR/450).

  • Fix xs.catalog.concat_data_catalogs for catalogs that have not been search yet. (PR/431).
  • Fix indicator computation using freq=2Q* by assuming this means a semiannual frequency anchored at the given month (pandas assumes 2 quarter steps, any of them anchored at the given month). (PR/431).
  • create_bounds_rotated_pole now uses the default value if the dataset has no north_pole_grid_longitude attribute, instead of crashing. (PR/455).
  • Rewrote the global tas data file with latest HDF5/h5py to avoid errors when using h5py 3.11 and hdf5 1.14.2. (PR/1861).
  • Remove reference of deprecated xclim functions (convert_calendar, get_calendar) and adapt the code for supporting xclim 0.52.2 and its subsequent development version. (PR/465). ### Breaking changes
  • convert_calendar in clean_up now uses xarray instead of xclim. Keywords aren't compatible between the two, but given that xclim will abandon its function, no backwards compatibility was sought. (PR/450).
  • attrs_to_remove and remove_all_attrs_except in clean_up now use real regex. It should not be too breaking since a fullmatch() is used, but * is now .*. (PR/450).
  • Python 3.9 is no longer supported. (PR/456).
  • Functions and arguments that were deprecated in xscen v0.8.0 or earlier have been removed. (PR/461).
  • pytest-xdist is now a development dependency. (PR/464).
  • xs.regrid.create_bounds_rotated_pole has been renamed to xs.regrid.create_bounds_gridmapping. (PR/467).
  • The weights_location argument in regrid_dataset is no longer positional. (PR/467).
  • The xs.regrid.create_mask function now requires explicit arguments instead of a dictionary. (PR/467). ### Internal changes
  • DataCatalog.to_dataset can now accept a preprocess argument even if create_ensemble_on is given. The user assumes calendar handling. (PR/431).
  • Include domain in weight_location in regrid_dataset. (PR/414).
  • Added pins to xarray, xclim, h5py, and netcdf4. (PR/414).
  • Add .zip and .zarr.zip as possible file extensions for Zarr datasets. (PR/426).
  • Explicitly assign coords of multiindex in xs.unstack_fill_nan. (PR/427).
  • French translations are compiled offline. A new check ensures no PR are merged with missing messages. (GH/342, PR/443).
  • Continued work to add tests. (PR/450).
  • Updated the cookiecutter template via cruft: (PR/452)
    • GitHub Workflows that use rely on PyPI-based dependencies now use commit hashes.
    • Dependabot will now group updates by type.
    • Dependencies have been updated and synchronized.
