New file grib2io/tables/section4_discipline20.py for new-ish GRIB2 discipline 20 (Health and Socioeconomic Impacts).
Added parameter tables for discipline 20 Added section 4 tables 4.234, 4.235, 4.236, 4.238, 4.239, 4.244, and 4.251. Updated shape of for entry 5 of earth_params dict to ellipsoid.
In make_grib2_tables/make-ncep-grib2-tables.sh, the earth_params table is now prefixed with "table_" like the other tables.
Fixed an issue with EarthRadius, EarthMajorAxis, EarthMinorAxis descriptor classes not providing values from earth_params table. Added EarthShape descriptor class.
Added earthShape metadata attribute to the Grib2Message object.
New functions get_shortnames() and get_metadata_from_shortname().
In grib2io/templates.py, mistakingly did not change the duplicated EarthRadius class to EarthShape. In grib2io/tables/__init__.py, using lru_cache decorator instead of cache since cache is available starting from Python 3.9. The functools documentation states that @cache == @lru_cache(maxsize=None).

* Adding support for GDT 32678 and 32769. In templates.py, adding template classes for templates 32678 and 32679. * Update for GDT 32769. initial support for generating lats and lons for grid 32769. this commit references issue #96 * Update for grib2io xarray backend Adding support to pass method_options keyword to the various array interpolation functions and accessor functions. This keyword will map to grib2io's interpolation functions with the same keyword argument name. This commit references issue #97 * Updating C sources from Cython Generated from Cython 3.0. * Update grib2io Added logic when creating a GRIB2 message from scratch, to populate the reference date/time information in section1 with default values of the UNIX epoch date. This avoids raising a ValueError with the datetime.datetime object. * Update for xarray backend Adding accessor function 'griddef' to return a grib2io.Grib2GridDef object from a Dataset or DataArray. * Update docs. [skip ci] * Update for grib2io xarray backend - Adding validDate coordinate variable - Adding fullName and shortName to data variables. - Changed message selection on 1 line to use isel() * Version bump to v2.0.1. * Update grib2io/__init__.py Change "import g2clib" to "import .g2clib". * Update docs and version bump to v2.0.2. * Fix for missing template numbers This commit fixes the missing template numbers in section arrays. Also adding property functions gdt, pdt, and drt as shortcuts. This commit references issue #101 * Update docs. * Fix for correct number of data points in section 3 section3[1] should hold the number of data points, generally that is nx*ny. This was not getting set when creating a Grib2Message object from scratch. Added 'sourceOfGridDefinition' and 'numberOfDataPoints' to section 3 metadata that is provided via __repr__(). this commit references issue #101 * Update docs. * 95 add support for drt 542 aecccsds compression (#103) * Adding support for DRT 5.42 Adding support for DRT 5.42 AEC/CCSDS compression. Other changes in g2clib Cython related to changes to g2c coming version 1.8.0 and also Cython major udate to v3.0 from 0.29... ref issue #95 [skip ci] * Clean up of code to support DRT 5.42. Using 'aec' as the string for this compression scheme. Removed "CCSDS" from descriptor classes and attributes. * Update setup.py Still getting conditions where g2c_incdir is not set, so I think this takes care of that....ugh. * Update for grib2io xarray backend Adding support to pass method_options keyword to the various array interpolation functions and accessor functions.

Added attributes for lower and upper limit scale factors and scaled values to product definition template classes 4.5 and 4.9. This commit references issue #105 Co-authored-by: Eric Engle <[email protected]> * Added VERSION file Updated setup.py to read from VERSION file. * Removal of Cython-generated C sources Removing Cython-generated C sources from git tracking. * Update MANIFEST.in Remove *.c Cython-generated sources. * Adding support for GDT 32678 and 32769. In templates.py, adding template classes for templates 32678 and 32679. * Update for grib2io/templates.py Changing metadata attr names... unitOfTimeRange -> unitOfForecastTime forecastTime -> valueOfForecastTime These new names are more consistent with attr names elsewhere and should be less confusing as end users should use leadTime attr which is a datetime.timedelta object. * Update for lat lon storage Changed storage object of lats and lons from a tuple in the data store to a dictionary with keys 'latitude' and 'longitude'. This is due to the Arakawa rotate grid (32769) that will generate rotation angles for vector quantities and we will want to store those as well. * Adding lat/lon generation for GDT 32769 Adding functions to support generation of lats and lons for GDT 32769. These functions have been adapted from the NCAR command langauge (ncl). This commit also adds a function to generate rotation angles for vector quantities. The angles should be applied to U/V-based grids in the following manner: formula_u : Uearth = sin(rot)*Vgrid + cos(rot)*Ugrid formula_v : Vearth = cos(rot)*Vgrid - sin(rot)*Ugrid This commit references issue #96 --------- Co-authored-by: Eric Engle <[email protected]> Co-authored-by: alcoat <[email protected]>
