grib2io v2.2.2

What's Changed

• Fixed a bug where grib2io was not properly opening Gzipped GRIB2 files by @EricEngle-NOAA in 95e397d
• Fixed an issue with the scenario where of calling flush_data() on a Grib2Message object created from a user (i.e. not read from file) would raise an error by @EricEngle-NOAA in 95e397d
• Fixed an issue with the scenario of calling pack() method for a Grib2Message object where data are None. Moving forward, pack() will attempt to pack data if it can be found (i.e. reading data from disk) by @EricEngle-NOAA in 95e397d
• Cleaned up logic of handling the Grib2MessageOnDiskArray object in the Grib2Message object when flushing unpacked data. Moving forward, the Grib2Message._data private attribute will be either None or numpy.ndarray and Grib2Message._ondiskarray will always be None or Grib2MessageOnDiskArray. by @EricEngle-NOAA in 95e397d

grib2io v2.2.1

What's Changed

• Fixed a bug in Grib2Message.interpolate() where num_threads was not being passed to the module-level function, grib2io.interpolate(). This caused the default value of 1 to always be used by @EricEngle-NOAA in dadabda

grib2io v2.2.0

What's Changed

• Fixed issue when opening GRIB2 files via the xarray backend by @TimothyCera-NOAA in #126
• Added support for MRMS GRIB2 files and custom MRMS GRIB2 tables File by @EricEngle-NOAA in #127
  • MRMS GRIB2 files are Gzipped. grib2io can now read Gzipped GRIB2 files, but this cannot be done using the xarray backend
• Cleanup of GRIB2 message indexing and allow for GRIB1 messages to be ignored by @EricEngle-NOAA in #129
  • Some ECMWF files contain both GRIB1 and GRIB2 messages

• Added to_grib2() xarray accessor method for xarray.Dataset and xarray.DataArray objects by @TimothyCera-NOAA in #136
• Improved performance when opening files by removing the use of a 1MB buffer (leftover from grib2io v1.x) and by making grib2io.open attrs levels and variables properties by @EricEngle-NOAA in 2fd5219 and 626e28e
• Added NCEP GRIB2 table version number by @EricEngle-NOAA in 01e3f62
• Changed Grib2Message.duration attribute from being None to datetime.timedelta(hours=0) by @EricEngle-NOAA in 9ef5e53
• Added properties min, max, mean, and median to the Grib2Message object by @EricEngle-NOAA in 24e4260

Details about writing to GRIB2 from the Xarray Backend

grib2io v2.2.0 introduces the ability to write GRIB2 files from the xarray backend via .to_grib2() accessor methods for xarray.Dataset and xarray.DataArray objects. At this time, this will only work if xarray objects originated from the grib2io xarray backend. The .to_grib2() accessor method leverages xarray attributes 'GRIB2IO_section*' that are the numeric GRIB2 metadata sections. Future updates to the grib2io xarray backend will further build out this functionality.
