We compare verified atmospheric mercury measurements against output from the GEOS-Chem photochemical transport model. We show the model is unable to reproduce measured atmospheric oxidized mercury concentrations, even in several cases where oxidation rates in the model are enhanced.

Precursor compounds must be present in the lower atmosphere for ozone to form. Ozone abatement strategies focus on reducing such precursors, but measuring and modeling are necessary to determine the most efficient way to do this. We show that the sensitivity of ozone to various precursors changes over the course of the winter. We also argue that similar seasonal changes probably occur in many regions of the Northern Hemisphere.

New sorbent materials are needed to preconcentrate atmospheric oxidized mercury for analysis by developing mass spectrometry methods. Chitosan, α-Al2O3, and γ-Al2O3 were tested for quantitative gaseous oxidized mercury sorption in ambient air under laboratory and field conditions. Although these materials sorbed gaseous oxidized mercury without sorbing elemental mercury in the laboratory, less oxidized mercury was recovered from these materials compared to cation exchange membranes in the field.

Short summary
Mercury (Hg) is a globally distributed neurotoxic pollutant. Atmospheric deposition is the main source of Hg in ecosystems. However, measurement biases hinder understanding of the origins and abundance of the more bioavailable oxidized form. We used an improved, calibrated measurement system to study air mass composition and transport of atmospheric Hg at a remote mountaintop site in the central US. Oxidized Hg originated upwind in the low to middle free troposphere under clean, dry conditions.

Short summary
We studied unusual winter air pollution in Utah's Uinta Basin, where ozone levels exceed safety standards despite cold temperatures. Using an air quality model, we found hydrocarbon compounds from oil and gas operations transform into formaldehyde and other chemicals during winter photochemical events. Light alkanes were the biggest contributors to pollution formation. Understanding these mechanisms helps identify compounds to target for emission reductions in oil and gas regions.
