Changelog for cfgrib

0.9.8.0 (unreleased)

  • Add support of experimental pyeccodes low-level driver by @b8raoult.

0.9.7.7 (2020-01-24)

  • Add support for forecastMonth in cf2cdm.translate_coords.

0.9.7.6 (2019-12-05)

  • Fix the README.

0.9.7.5 (2019-12-05)

  • Deprecate ensure_valid_time and the config option preferred_time_dimension that are now better handled via time_dims.

0.9.7.4 (2019-11-22)

  • Add more options to time_dims forecasts products may be represented as ('time', 'verifying_time') or ('time', 'forecastMonth'). See: #97.

0.9.7.3 (2019-11-04)

  • Add support for selecting the time coordinates to use as dimensions via time_dims. Forecasts products may be represented as ('time', 'step') (the default), ('time', 'valid_time') or ('valid_time', 'step'). See: #97.
  • Reduce the in-memory footprint of the FieldIndex and the size of .idx files.

0.9.7.2 (2019-09-24)

  • Add support to read additional keys from the GRIB files via read_keys, they appear in the variable attrs and you can filter_by_keys on them. This is a general solution for all issues where users know the name of the additional keys they are interested in. See: #89 and #101.

0.9.7.1 (2019-07-08)

  • Fix a bytes-in-the-place-of-str bug when attempting to write a GRIB on Windows. See: #91.
  • Honor setting indexpath in open_datasets, See: #93.

0.9.7 (2019-05-27)

  • Much improved cfgrib.open_datasets heuristics now reads many more heterogeneous GRIB files. The function is now a supported API. See: #63, #66, #73 and #75.
  • Fix conda dependencies on Python 2 only package, See: #78.

0.9.7rc1 (2019-05-14)

  • Drop support for Python 2, in line with xarray 0.12.0. The 0.9.6.x series will be supported long term for Python 2 users. See: #69.
  • Sync internal ecCodes bindings API to the one in eccodes-python. See: #81.
  • Source code has been formatted with black -S -l 99.
  • Added initial support for spectral coordinates.

0.9.6.2 (2019-04-15)

  • Improve merging of variables into a dataset. See: #63.

0.9.6.1.post1 (2019-03-17)

  • Fix an issue in the README format.

0.9.6.1 (2019-03-17)

  • Fixed (for real) MULTI-FIELD messages, See: #45.
  • Added a protocol version to the index file. Old *.idx files must be removed.

0.9.6.post1 (2019-03-07)

  • Fix an important typo in the README. See: #64.

0.9.6 (2019-02-26)

  • Add support for Windows by installing ecCodes via conda. See: #7.
  • Added conda-forge package. See: #5.

0.9.5.7 (2019-02-24)

  • Fixed a serious bug in the computation of the suggested filter_by_keys for non-cubic GRIB files. As a result cfgrib.xarray_store.open_datasets was not finding all the variables in the files. See: #54.
  • Fixed a serious bug in variable naming that could drop or at worse mix the values of variables. Again see: #54.
  • Re-opened #45 as the fix was returning wrong data. Now we are back to dropping all variable in a MULTI-FIELD except the first.

0.9.5.6 (2019-02-04)

  • Do not set explicit timezone in units to avoid crashing some versions of xarray. See: #44.

0.9.5.5 (2019-02-02)

  • Enable ecCodes implicit MULTI-FIELD support by default, needed for NAM Products by NCEP. See: #45.
  • Added support for depthBelowLand coordinate.

0.9.5.4 (2019-01-25)

  • Add support for building valid_time from a bad time-step hypercube.

0.9.5.3 (2019-01-25)

  • Also convert is valid_time can index all times and steps in translate_coords.

0.9.5.2 (2019-01-24)

  • Set valid_time as preferred time dimension for the CDS data model.
  • Fall back to using the generic GRIB2 ecCodes template when no better option is found. See: #39.

0.9.5.1 (2018-12-27)

  • Fix the crash when using cf2cdm.translate_coords on datasets with non-dimension coordinates. See: #41.
  • Added a cfgrib script that can translate GRIB to netCDF. See: #40.

0.9.5 (2018-12-20)

  • Drop support for xarray versions prior to v0.11 to reduce complexity. (This is really only v0.10.9). See: #32.
  • Declare the data as CF-1.7 compliant via the Conventions global attribute. See: #36.
  • Tested larger-than-memory and distributed processing via dask and dask.distributed. See: #33.
  • Promote write support via cfgrib.to_grib to Alpha. See: #18.
  • Provide the cf2cdm.translate_coords utility function to translate the coordinates between CF-compliant data models, defined by out_name, units and store_direction. See: #24.
  • Provide cfgrib.__version__. See: #31.
  • Raise with a better error message when users attempt to open a file that is not a GRIB. See: #34.
  • Make 2D grids for rotated_ll and rotated_gg gridType's. See: #35.

0.9.4.1 (2018-11-08)

  • Fix formatting for PyPI page.

0.9.4 (2018-11-08)

  • Saves one index file per set of index_keys in a much more robust way.
  • Refactor CF-encoding and add the new encode_cf option to backend_kwargs. See: #23.
  • Refactor error handling and the option to ignore errors (not well documented yet). See: #13.
  • Do not crash on gridType not fully supported by the installed ecCodes See: #27.
  • Several smaller bug fixes and performance improvements.

0.9.3.1 (2018-10-28)

  • Assorted README fixes, in particular advertise index file support as alpha.

0.9.3 (2018-10-28)

  • Big performance improvement: add alpha support to save to and read from disk the GRIB index produced by the full-file scan at the first open. See: #20.

0.9.2 (2018-10-22)

  • Rename coordinate air_pressure to isobaricInhPa for consistency with all other vertical level coordinates. See: #25.

0.9.1.post1 (2018-10-19)

  • Fix PyPI description.

0.9.1 (2018-10-19)

  • Change the usage of cfgrib.open_dataset to allign it with xarray.open_dataset, in particular filter_by_key must be added into the backend_kwargs dictionary. See: #21.
