Abstract |
The Acid Rain Mountain Mesoscale Model (ARM3) is a mesoscale acid deposition/air quality model that was developed for calculating incremental acid deposition (sulfur and nitrogen species) and pollutant concentration impacts in complex terrain. The model was set up for operation within the Rocky Mountain region. The model contains many simplications that were necessary to meet operational requirements. New research studies to provide information on mesoscale flow over complex terrain and atmospheric chemistry in the western region would be necessary to help resolve questions concerning the validity of the model simplifications. The ARM3 consists of six components. Of them, the mesoscale meteorological model contains a new diagnostic wind model that accounts for the kinematic, deflection, and thermal effects that alter the flow fields due to complex terrain. The Lagrangian acid deposition/air quality model has the following attributes: two options for calculating plume height above ground; three options for determining dispersion rates, including one that accounts for terrain roughness; a dry deposition algorithm based on the resistance approach; a wet deposition algorithm based on the scavenging approach; and two options for calculating chemical transformation. |
