Organic peroxides (POs) are organic molecules with one or more peroxide (− O–O−)
functional groups. POs are commonly regarded as chemically labile termination products …

Highly oxygenated organic molecules (HOM) are formed in the atmosphere via autoxidation
involving peroxy radicals arising from volatile organic compounds (VOC). HOM condense on …

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 …

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 …

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

The hydroxyl radical (• OH) is one of the most powerful oxidizing agents, able to react
unselectively and instantaneously with the surrounding chemicals, including organic …

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 …

The chemistry of isoprene degradation in the Master Chemical Mechanism (MCM) has been
systematically refined and updated to reflect recent advances in understanding, with these …

Ozone pollution in the Southeast US involves complex chemistry driven by emissions of
anthropogenic nitrogen oxide radicals (NO x≡ NO+ NO 2) and biogenic isoprene. Model …

The self-cleaning or oxidation capacity of the atmosphere is principally controlled by
hydroxyl (OH) radicals in the troposphere. Hydroxyl has primary (P) and secondary (S) …
