METplus version 3.0

General

• Moved to using Python 3.6.3 or higher.
• Reorganization of use case directory structure - see https://ncar.github.io/METplus/Users_Guide/usecases.html
• Support for Python Embedding:
  • For supplying gridded input data to MET tools: PCPCombine, RegridDataPlane, PointStat, etc.
  • For MET tools that accept multiple input files: SeriesAnalysis, EnsembleStat,and MTD
  • For reading point observations via ASCII2NC
• Documentation moved online using GitHub Pages: https://ncar.github.io/METplus
  • Addition of Contributor's Guide
• Logging:
  • Enhanced log output to include MET command and required environment variables in the MET tool log file. (#374)
  • Improved logging to help debugging by listing expected file path and reporting error count for each wrapper (#289)

Wrapper Specific

• ASCII2NC (#263)
  • New wrapper
• SeriesAnalysis (#381)
  • New wrapper
• PyEmbedIngester (#281)
  • New wrapper
  • Added to allow python embedding for multiple data sources
• PcpCombine
  • Supports custom user-defined commands to build atypical use case calls (#212)
  • Supports bucket dumping (#305)
  • Supports constant initialization time for processing forecast data
• PB2NC
  • New configuration variables PB2NC_VALID_[BEG/END] to set -valid_beg and -valid_end command line args (#338)
• PointStat
  • New configuration variables POINT_STAT_OBS_VALID_[BEG/END] to set -obs_valid_beg and -obs_valid_end command line arguments.
• RegridDataPlane
  • Support gaussian command line arguments via METplus (#367)

Configuration

• User environment variables ([user_env_vars]) and [FCST/OBS]_VAR_[NAME/LEVEL/OPTIONS] now support filename template syntax, i.e. {valid?fmt=%Y%m%d%H} (#267)
• Added support for month, year, and sub-hourly intervals for [INIT/VALID]_INCREMENT and LEAD_SEQ (#292, #298)
• Configuration Name Changes:
  • Many configuration variable names have changed to conform to naming conventions (#306, #312, etc).
  • Added utilities and instructions to assist with transitioning old configuration files to run using METplus 3.0: https://ncar.github.io/METplus/Users_Guide/installation.html#updating-configuration-files-handling-deprecated-configuration-variables
• New General configuration options:
  • _REGRID_TO_GRID options for GridStat, EnsembleStat, MODE, MTD, SeriesAnalysis (#339)
  • _OUTPUT_PREFIX for GridStat, PointStat, EnsembleStat, MODE, and MTD (#351).
  • Support wrapper specific field info lists - [FCST/OBS]_VAR[NAME/LEVELS/OPTIONS/THRESH] supported to allow different lists for each wrapper. Applies to GridStat, PointStat, EnsembleStat, MODE, and MTD (#378).
  • Support for custom string list for each wrapper to allow tool to be called multiple times per run time (#383). See https://ncar.github.io/METplus/Users_Guide/systemconfiguration.html#custom-looping

Bugfixes

• ExtractTiles wrapper now checks for empty file list rather than an empty directory, (#277)
• PCPCombine subtract mode will call add method with 1 file if processing accumulation data and the lead time is equal to the desired accumulation
• PCPCombine add mode forecast GRIB input
• PCPCombine sum mode no longer fails when input level is not explicitly specified
• PCPCombine now sets additional field options in -add mode using [FCST/OBS]_PCP_COMBINE_INPUT_OPTIONS (#390)
• Feature relative config files no longer defines variable names and levels via VAR_LIST. Now employ the same syntax as other wrappers: BOTH_VAR1_NAME, BOTH_VAR1_LEVELS, BOTH_VAR2_NAME, BOTH_VAR2_LEVELS, etc. (#143)
• SeriesAnalysis wrappers, use the STAGING_DIR rather than the TMP dir for storing intermediate files and remove these files before exiting the wrapper. (#341)
• SeriesByLead wrapper no longer creates temporary subdirectories based on the current process id, as this prevented the wrapper from being run stand-alone using pre-existing data (#332)
• SeriesByInit wrapper no longer creates temporary subdirectories based on the current process id, as this prevented the wrapper from being run stand-alone using pre-existing data (#333)
