v0.14.1

New Features

• Added new methods to clisops.core.regrid.Grid
  • Added possibility to apply land or ocean mask if present in the file
  • Adapted method from ESMF to detect smashed cells
  • Masking degenerate (i.e. collapsed and smashed) cells
  • Dropping lat/lon bounds if an integrity check fails
  • Added a few attributes to the Grid object
• clisops.ops.regrid: added option to request a land/sea mask for the output grid
• clisops.utils.dataset_utils
  • Added function determine_lon_lat_range to determine the min. and max. lat and lon values
  • Added function fix_unmasked_missing_values_lon_lat to identify and mask yet unmasked missing values in lat and lon arrays
  • Added force parameter to cf_convert_between_lon_frames

Bug Fixes

• clisops.utils.dataset_utils
  • Fixed issue in cf_convert_between_lon_frames causing the longitude frame to not be adjusted in case of NaNs in the longitude array
  • Addressed issues in generate_bounds_curvilinear
    • latitudes are now clipped above 90 or below -90 degrees north
    • longitudes are converted to longitude frame -180, 180
    • longitude bounds are adjusted at the Greenwich meridian or anti meridian to avoid grid cells wrapping once or more times around the globe
    • Bounds are generated significantly faster due to making use of index slicing and numpy.vectorize

Breaking Changes

• Adapted functions from roocs_utils.xarray_utils.xarray_utils into clisops.utils.dataset_utils
  • get_coord_by_type now returns the name of the coordinate variable and not the coordinate variable
  • get_coord_by_type optionally returns a list with further matches for the coordinate variable
  • get_coord_by_type does no longer raise an exception when more than one coordinate variable matches the requested type
  • get_coord_by_type raises ValueError instead of Exception when the coordinate type is unknown
  • detect_coordinate raises KeyError instead of AttributeError if no coordinate could be detected
  • detect_gridtype raises ValueError for unsupported grid types rather than InvalidParameterValue and Exception
• clisops.core.regrid
  • Grid.detect_coordinate: raises KeyError instead of AttributeError if no coordinate could be detected
• clisops.ops.regrid
  • Regrid._calculate: issues UserWarning instead of letting clisops.core.Weights.__init__ raise an Exception when input and output grid are alike

Other Changes

• The testing suite has been refactored to make better use of context handlers when opening files with xarray, preventing synonymous read errors and improving the overall performance of the tests.
• Several tests that were failing due to significantly long runtimes have been marked as slow and are now skipped by default.
• GitHub Workflows now use a timeout of 20 minutes for the build suite to prevent hanging builds.
