CMAQ

Abstract Researchers who perform air quality modeling studies usually do so on
a regional scale. Typically, the boundary conditions are generated by another model
which might have a different chemical mechanism, spatial resolution, and/or map
projection. Hence, a necessary conversion/interpolation takes place which introduces
additional error. In a broader sense, air pollution is a global issue, thus, limited area
modeling on the regional scale is not well suited to represent long-range transport
from key source regions in other parts of the world. We have developed a prototype
system to link the Model for Prediction Across Scales—Atmosphere (MPAS-A)
with the Community Multiscale Air Quality (CMAQ) model to address these shortcomings. Pollutant transport is conducted within MPAS-A, rather than in CMAQ,
