Basic Description

5.0km WRF-ARW: Run every 12 hours out to 48 hours using NAM initial conditions and boundary conditions. The default domain is centered over New Mexico.

1.0km WRF-ARW: Run every 6 hours out to 24 hours using NAM initial conditions and boundary conditions. The default domain is centered over the Albuquerque and Santa Fe metro areas. The domain is moved to support decision support activities.
