Release Notes for METv1.1

Build process

  • Add support for building MET on an IBM and provide a sample IBM Makefile.
  • Add support for use of the GNU gfortran compiler.
  • Supply compiler flags for building MET as a 32-bit executable on 64-bit machines.
  • Reorganize Makefile configuration process.
  • Remove several compilation warning messages.

Library code

  • Several bug fixes.
  • Allow the use of environment variables in the configuration files.
  • Improve the algorithm for computing percentiles to include interpolating between values when necessary.

PB2NC Tool

  • Add "-pbfile" command line option to process multiple PREPBUFR files.
  • Add the "-valid_beg" and "-valid_end" command line options to explicitly set the retention time window.
  • Simplify format of the output NetCDF file by removing variables that are not used by Point-Stat.

ASCII2NC Tool

  • Add new tool for converting ASCII observations to NetCDF for input into Point-Stat.

PCP-Combine Tool

  • Add "-add" command line option to add together accumulation intervals from two Grib files directly.
  • Add "-subtract" command line option to take the difference of accumulation intervals from two Grib files directly.
  • Add "-gc" command line option to allow the user to specify which grib code to use.

    • Point-Stat Tool

    • Add "-ncfile" command line option to process multiple NetCDF point observation files.
    • Add the ability to dump out the matched pair data (forecast, observation, climatology) directly to ASCII and VSDB files.
    • Add output matched pair (MPR) line type to store matched pair data.
    • Compute bootstrap confidence intervals for the Contingency Table Statistics (CTS) and Continuous Statistics (CNT) line types.
    • Add 5 parameters to the configuration file for options related to computing bootstrap confidence intervals.
    • Add "rank_corr_flag" configuration parameter to disable the computation of Spearman's Rank Correlation Coefficient and Kendall's Tau Correlation Coefficient to improve runtime performance.
    • Add "tmp_dir" configuration parameter to specify the directory where temporary files should be written by Point-Stat.
    • Allow the "mask_grids" configuration parameter to be set to "FULL" to indicate that statistics should be computed over the entire domain.

    Grid-Stat Tool

    • Add the ability to perform neighborhood verification.
    • Add 3 parameters to the configuration file for options related to neighborhood verification.
    • Add 3 output line types related to neighborhood verification: Neighborhood Contingency Table Counts (NBRCTC)
      Neighborhood Contingency Table Statistics (NBRCTS)
      Neighborhood Continuous Statistics (NBRCNT)
    • Compute bootstrap confidence intervals for the Contingency Table Statistics (CTS and NBRCTS) and Continuous Statistics (CNT and NBRCNT) line types.
    • Add 5 parameters to the configuration file for options related to computing bootstrap confidence intervals.
    • Add "rank_corr_flag" configuration parameter to disable the computation of Spearman's Rank Correlation Coefficient and Kendall's Tau Correlation Coefficient to improve runtime performance.
    • Add "tmp_dir" configuration parameter to specify the directory where temporary files should be written by Point-Stat.
    • Allow the "mask_grids" configuration parameter to be set to "FULL" to indicate that statistics should be computed over the entire domain.

    MODE Tool

    • Add "met_data_dir" configuration parameter to point to the location of static data files MODE needs for plotting. It should be set if MODE is moved from its original installation directory.
    • Enhance the way colorbars are plotted in the PostScript output and add a "stride_length" configuration parameter to indicate how often labels should be plotted alongside the colorbar.

    VSDB-Analysis Tool

    • Add job type "vsdb_job_aggr_mpr" to process the matched pair output data from Point-Stat.
    • Add 6 parameters to the configuration file for options related to computing bootstrap confidence intervals.
    • Add "init_hour" configuration parameter to filter out data by the model initialization hour.
    • Add "rank_corr_flag" configuration parameter to disable the computation of Spearman's Rank Correlation Coefficient and Kendall's Tau Correlation Coefficient to improve runtime performance.

    MODE-Analysis Tool

    • Add "version" configuration parameter to store the version number.
