PROGRAM rad_3dvar_to_dart

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.

obs_seq_out_file_name

character(len=129)

File name for output observation sequence file.

calendar_type

integer

Files

  • input namelist ; input.nml

  • Input observation file; qc_radr_3dvar_2002083100.dat

  • Output observation file; obs_seq.out

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.
