TL;DR: In this article, the authors investigated mass concentrations of particle water and related particle pH for ambient fine-mode aerosols sampled in a relatively remote Alabama forest during the Southern Oxidant and Aerosol Study (SOAS) in summer and at various sites in the southeastern US during different seasons, as part of the Southeastern Center for Air Pollution and Epidemiology (SCAPE) study.

TL;DR: The Community Multiscale Air Quality model is updated to predict isoprene aerosol from epoxides produced under both high- and low-NOx conditions, which represents a significant source of organic carbon in the lower 2 km of the atmosphere and captures the abundance of 2-methyltetrols relative to organosulfates during the simulation period.

TL;DR: In this paper, the authors quantify the source contributions to surface PM2.5 pollution over North China from January 2013 to 2015 using the GEOS-Chem chemical transport model and its adjoint with improved model horizontal resolution (1/4° × 5/16°) and aqueous phase chemistry for sulfate production.

TL;DR: In this paper, the authors evaluate the potential value of a new geostationary remote sensing instrument (GCIRI) for providing constraints on NH3 fluxes through multiple Observing System Simulation Experiments (OSSEs).

TL;DR: In this article, an updated diurnal variability scheme for NH3 livestock emissions and evaluate the recently developed MASAGE_NH3 bottom-up inventory is presented. But the authors do not consider the effect of NH3 emissions from primary sources.
