Isoprene carries approximately half of the flux of non-methane volatile organic carbon
emitted to the atmosphere by the biosphere. Accurate representation of its oxidation rate and …

Many atmospheric chemicals occur in the gas phase as well as in liquid cloud droplets and
aerosol particles. Therefore, it is necessary to understand the distribution between the …

Photochemistry is a fundamental process of planetary atmospheres that regulates the
atmospheric composition and stability. However, no unambiguous photochemical products …

An overview of the Community Earth System Model Version 2 (CESM2) is provided,
including a discussion of the challenges encountered during its development and how they …

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 …

Atmospheric methane grew very rapidly in 2014 (12.7±0.5 ppb/year), 2015 (10.1±0.7
ppb/year), 2016 (7.0±0.7 ppb/year), and 2017 (7.7±0.7 ppb/year), at rates not observed …

Atmospheric oxidation of sulfur dioxide (SO2) forms sulfate-containing aerosol particles that
impact air quality, climate, and human and ecosystem health. It is well-known that in-cloud …

The atmospheric methane trend is not fully understood. Here we investigate the role of the
main sink, the main natural source, and anthropogenic emissions on the methane growth …

In contrast to summer smog, the contribution of photochemistry to the formation of winter
haze in northern mid-to-high latitude is generally assumed to be minor due to reduced solar …

Methane is the second strongest anthropogenic greenhouse gas and its atmospheric
burden has more than doubled since 1850. Methane concentrations stabilized in the early …
