CMAQ-MetEmis: Development of Dynamic Meteorology-Induced Emissions Coupler (MetEmis) for Onroad Mobile Sources in the Community Multiscale Air Quality (CMAQ) Bok Baek

Short summary
To enable the direct feedback effects of aerosols and local meteorology in an air quality modeling system without any computational bottleneck, we have developed an inline meteorology-induced emissions coupler module within the U.S. Environmental Protection Agency’s Community Multiscale Air Quality modeling system to dynamically model the complex MOtor Vehicle Emission Simulator (MOVES) on-road mobile emissions inline without a separate dedicated emissions processing model like SMOKE.
