[EricEngle-NOAA]

What's Changed

• Fixed issue when opening GRIB2 files via the xarray backend by @TimothyCera-NOAA in Set kwargs["_xarray_backend"], an assert to ValueError, removed if. #126
• Added support for MRMS GRIB2 files and custom MRMS GRIB2 tables File by @EricEngle-NOAA in MRMS GRIB2 File #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 Cleanup of GRIB2 message indexing and allow for GRIB1 message to be ignored #129
  • Some ECMWF files contain both GRIB1 and GRIB2 messages
• Add support for PDT 4.32 by @EricEngle-NOAA in Add support for PDT 4.32 and change PDT class structure #130

• 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

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.
