Short summary
We test new parameterizations for secondary inorganic aerosols in GISS ModelE. To evaluate the model performance, we use measurements of these aerosols and gaseous precursors from surface and aircraft measurements over the USA and Europe. We show that considering the size distribution of these particles, as well as a variety of formation pathways, is important. Overall, our model underestimates the aerosol mass compared to measurements, while gaseous precursors are overestimated.
