Source Attribution of PM_2.5 Health Benefits Over Northern Hemisphere Using Adjoint of Hemispheric CMAQ. [PDF]

Geohealth
Abstract The adjoint of the U.S. EPA's Community Multiscale Air Quality (CMAQ) model is extended for hemispheric scale applications and is used to estimate location‐specific health impacts from primary PM2.5, and PM2.5 precursor emissions (NH3, NOX and SO2). We estimate the monetized health burden due to mortality caused by chronic PM2.5 exposure among

A multiphase CMAQ version 5.0 adjoint [PDF]

Geoscientific Model Development, 2019
Abstract. We present the development of a multiphase adjoint for the Community Multiscale Air Quality (CMAQ) model, a widely used chemical transport model. The adjoint model provides location- and time-specific gradients that can be used in various applications such as backward sensitivity analysis, source attribution, optimal pollution control, data ...
