Version release notes ()

Version 10.0.0-beta3 release notes (20210127)

  • Bugfixes:

    • Correct the climatological CDF values in the Grid-Stat NetCDF matched pairs output files, and correct the climatological probability values for climatgological distribution percentile (CDP) threshold types (#1638).
    • Apply the GRIB ensemble filtering option (GRIB_ens) whenever specified by the user (#1604).

  • Repository and build:

    • Update the MET unit test logic by unsetting environment variables after each test to provide a clean environment for the next (#1624).

  • Documentation:

    • Update the Grid-Diag documentation to clarify the -data command line option (#1611).
    • Documentation updates to correct typos and apply consistent formatting (#1455).
    • Correct the definition of H_RATE and PODY in MET User's Guide Appendix C (#1631).

  • Library code:

    • When reading MET NetCDF files, parse the "init_time" and "valid_time" attributes (#1346).
    • Python embedding enhancements:
      • Complete support for Python XArray embedding (#1534).
      • Correct error messages from Python embedding (#1473).

  • Application code:

    • Enhance Plot-Point-Obs to support regridding in the config file (#1627).
    • Update ASCII2NC and Point2Grid to create empty output files for zero input observations instead of erroring out (#1630).
    • Point2Grid Tool:
      • Improve the Point2Grid runtime performance (#1421).
      • Process point observations by variable name instead of GRIB code (#1408).
      • Support the 2-dimensional time variable in Himawari data files (#1580).
    • TC-Gen Tool:
      • Overhaul the Tropical Cyclone genesis matching logic, add the development and operational scoring algorithms, and add many config file options (#1448).
      • Add config file options to filter data by initialization time (init_inc and init_exc) and hurricane basin (basin_mask) (#1626).
      • Add the genesis matched pair (GENMPR) output line type (#1597).
      • Add a gridded NetCDF output file with counts for genesis events and track points (#1430).

Version 10.0.0-beta2 release notes (20201207)

  • Repository and build:

    • Switch from tagging releases as met-X.Y.Z to vX.Y.Z instead (#1541).
    • Switch to consistent vX.Y.Z version numbering, from v10.0 to v10.0.0 (#1590).
    • Run the nightly build as the shared met_test user (#1116).

  • Documentation:

    • Update comments at the top of each MET config file directing users to the MET User's Guide (#1598).
    • Migrate content from README and README_TC in data/config to the MET User's Guide (#1474).
    • Add version selector to the Sphinx documentation page (#1461).
    • Make bolding consistent across the documentation (#1458).
    • Implement hanging indents for references (#1457).
    • Correct typos and spelling errors (#1456).

  • Library code:

    • Enhance support for rotated latlon grids and update related documentation (#1574).
    • Update the NCL-derived color tables (#1568).
    • Parse the -v and -log options prior to application-specific command line options (#1527).
    • Treat gridded fields of entirely missing data as missing files and fix python embedding to call common data processing code (#1494).

  • Application code:

    • Overhaul the plot_point_obs tool to make it highly configurable (#213, #1528, and #1052).
    • Add new ioda2nc tool (#1355).
