Effect of Dust Morphology on Aerosol Optics in the GEOS‐Chem Chemical Transport Model, on UV‐Vis Trace Gas Retrievals, and on Surface Area Available for Reactive Uptake Open
Many chemical transport models treat mineral dust as spherical. Solar backscatter retrievals of trace gases (e.g., OMI and TROPOMI) implicitly treat mineral dust as spherical. The impact of the morphology of mineral dust particles is studi…

Variable effects of spatial resolution on modeling of nitrogen oxides Open
The lifetime and concentration of nitrogen oxides (NOx) are susceptible to nonlinear production and loss and to the resolution of a chemical transport model (CTM). This is due to the strong spatial gradients of NOx and the dependence of it…
