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

This namelist is read from the file input.nml. Namelists start with an ampersand '&' and terminate with a slash '/'. Character strings that contain a '/' must be enclosed in quotes to prevent them from prematurely terminating the namelist.

&rad_3dvar_to_dart_nml
   var_file = 'qc_radr_3dvar_2002083100.dat',
   obs_seq_out_file_name = 'obs_seq.out',
   calendar_type = 3

Item Type Description
var_file character(len=129) This is the name of the file containing MM5 3D-VAR 2.0 Radar observations.
obs_seq_out_file_name character(len=129) File name for output observation sequence file.
calendar_type integer Calendar type. We recommend using 3 (GREGORIAN).

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

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