Machine learning (ML) techniques applied to chemical reactions have a long history. The
present contribution discusses applications ranging from small molecule reaction dynamics …

Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the
acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the …

Atmospheric deposition of inorganic nitrogen is critical to the function of ecosystems and
elemental cycles. During the industrial period, humans have doubled the amount of …

Gaseous organic compounds, mainly volatile organic compounds (VOCs), have become a
wide concern in various indoor environments where we spend the majority of our daily time …

Atmospheric acidity is increasingly determined by carbon dioxide and organic acids,–.
Among the latter, formic acid facilitates the nucleation of cloud droplets and contributes to …

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 …

Criegee intermediates (CIs), carbonyl oxides formed in ozonolysis of alkenes, play key roles
in the troposphere. The decomposition of CIs can be a significant source of OH to the …

Abstract The Goddard Earth Observing System composition forecast (GEOS‐CF) system is a
high‐resolution (0.25°) global constituent prediction system from NASA's Global Modeling …

Stabilized Criegee intermediates (SCI) are reactive oxygenated species formed in the
ozonolysis of hydrocarbons. Their chemistry could influence the oxidative capacity of the …

We use an ensemble of surface (EPA CSN, IMPROVE, SEARCH, AERONET), aircraft (SEAC
4 RS), and satellite (MODIS, MISR) observations over the southeast US during the summer …
