Overview

Several programs for converting radar observations into DART obs_seq format exist, and will be placed in this directory when they are ready for distribution. Observations generated by these programs have been successfully assimilated with weather models in the DART framework.

This directory currently contains a program for generating synthetic radar observations for a WSR-88D (NEXRAD). It can generate reflectivity and/or doppler radial velocity observations with clear-air or storm sweep patterns, for testing or for OSSEs (Observing System Simulation Experiments).

There are challenges to working with radar data; for more information contact us.


DATA SOURCES

 


PROGRAMS

create_obs_radar_sequence generates one or more sets of synthetic radar observations. Change into the work subdirectory and run quickbuild.csh to build this program.

Many DART users working with radar observations are using the WRF Weather and Research Forecast model. See the WRF tests directory for pointers to data to run a radar test case.

In addition to the programs available in the DART distribution, the following external program produces DART observation sequence files:


KNOWN BUGS

none


FUTURE PLANS

none
