Configuration

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)
