Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

New particle formation of liquid or solid nanoparticles from gas-phase precursors is a
decisive process in Earth's atmosphere and is considered one of the largest uncertainties in …

Short‑lived climate forcers (SLCFs) affect climate and are, in most cases, also air pollutants.
They include aerosols (sulphate, nitrate, ammonium, carbonaceous aerosols, mineral dust …

Abstract The Whole Atmosphere Community Climate Model version 6 (WACCM6) is a major
update of the whole atmosphere modeling capability in the Community Earth System Model …

The evolution of tropospheric ozone from 1850 to 2100 has been studied using data from
Phase 6 of the Coupled Model Intercomparison Project (CMIP6). We evaluate long-term …

Atmospheric oxidation of isoprene, the most abundantly emitted non-methane hydrocarbon,
affects the abundances of ozone (O 3), the hydroxyl radical (OH), nitrogen oxide radicals …

Abstract The Community Earth System Model version 2 (CESM2) includes three main
atmospheric configurations: the Community Atmosphere Model version 6 (CAM6) with …

Chemical transport models have historically struggled to accurately simulate the magnitude
and variability of observed organic aerosol (OA), with previous studies demonstrating that …

Wildfire smoke, consisting primarily of organic aerosols, has profound impacts on air quality,
climate and human health. Wildfire organic aerosol evolves over long-time photochemical …

Ultraviolet (UV) radiation drives the net production of tropospheric ozone (O3) and a large
fraction of particulate matter (PM) including sulfate, nitrate, and secondary organic aerosols …
