Output files

Goal: Give an overview of the output files and folders created by DART-WRF.

Forecast files

Forecast history files are stored per init time in /<experiment>/YYMMDD_HHMM/<ens>/wrfout_d0*, as set in the parameter dir_archive of dartwrf.utils.Config. The file format is NetCDF.

Assimilation files

Diagnostics (obs_seq files) are stored in /<experiment>/diagnostics/, as defined in the parameters pattern_obs_seq_out and pattern_obs_seq_final of dartwrf.utils.Config. Files are typically named %Y-%m-%d_%H:%M_obs_seq.final. The file is readable in a text editor. To open it in Python as a pandas DataFrame, use dartwrf.obs.obsseq or pyDARTdiags.

Analysis files in NetCDF format are stored per assimilation time in /<experiment>/YYMMDD_HHMM/, e.g. output_mean.nc or filter_restart_d01.0001 (one file per ensemble member). Which files are output by DART is set in the DART namelist, settable through the dart_nml parameter, see DART docs.
