OVERVIEW

Programs to convert MM5 3D-VAR 2.0 Radar data files into DART observation sequence files. The capability of the program is limited to DOPPLER_RADIAL_VELOCITY and RADAR_REFLECTIVITY.

NAMELIST

We adhere to the F90 standard of starting a namelist with an ampersand '&' and terminating with a slash '/'.

namelist / wrf_3dvar_tf_dart_nml /  &
    wrf_3dvar_file, obs_seq_out_file_name, calendar_type

Discussion

This namelist is read in a file called input.nml
Contents Type Description
wrf_3dvar_file character(len=129) This is the name of the file containing MM5 3D-VAR 2.0 Radar observations. Default is 'qc_radr_3dvar_2002083100.dat'.
obs_seq_out_file_name character(len=129) File name for output observation sequence file. Default is 'obs_seq.out'.
calendar_type integer Calendar type. We recommend (GREGORIAN = 3) for WRF, which is the default.



FILES

File formats

input.nml and qc_radr_3dvar_2002083100.dat are ASCII files. obs_seq.out is either ASCII or binary, depending on the logical write_binary_obs_sequence, which is the namelist entry for obs_sequence_mod.

FUTURE PLANS

  • Use the preprocessor to include the observation list provided by obs_kind_mod.
  • Add the capability to convert from DART to MM5 3D-VAR 2.0 Radar data file format.
