RAMS is run operationally over the East Tennessee region with two grid domains.
The first grid uses a 32 km grid with 26 vertical levels evaluared over a 1500 by 1500 km domain. The second grid uses a 16 km grid with 26 vertical levels evaluated over a 800 by 800 km domain as illustrated in the attached plot. At this time, data from ATDD's regional weather network is not used in the RAMS iritialization. However, the site data are used in an ongoing evaluation of RAMS forecast skill for the East Tennessee Valley.
