RAMS is used to support air quality research.
RAMS has also been evaluated for air pollution deposition onto the Chesapeake using the buoy derived fluxed and deposition velocities there. Special software developed at ARL allows the user to initialize RAMS anywhere in the world using customized packed meteorological fields and global land and water surface data sets. The ARL RAMS operational emergency response forecasting system for air quality is described in more detail in Draxler, et al. The RAMS turbulence parameterization has been modified for air quality applications and deposition velocity of HNO3 onto the Chesapeake Bay has been added. RAMS is run operationally over the Chesapeake bay with a finest mesh of 4 km over a 296 by 376 km domain and 26 vertical levels.
