Abstract

Several improvements to the representations of clouds, aerosols, and cloud-aerosol interactions planned for the ACME V1 model have been implemented or are underway. In order to improve the simulated concentrations of smaller aerosol particles (< 100 nm), the treatments of H2SO4 vapor production and loss have been modified to use a parallel time-split approach. H2SO4 vapor strongly affects new particle formation, and because of its short lifetime it is sensitive to the time splitting.  Simulated aerosol number concentrations are now in much better agreement with observations.
