CO2 and N2O Emissions From Vehicles in Seoul Megacity, South Korea: Insights From Mixing Ratio and Stable Isotope Ratios

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Vehicular traffic is a major source of anthropogenic greenhouse gases in megacities; however, real‐world constraints on vehicle‐derived N2O emissions and their isotopic characteristics remain limited. Methods Air samples were collected from three tunnels and urban background sites (a university campus and mountain) in Seoul, South ...

A 400‐Year Antarctic Ice‐Core Perchlorate Record Reveals Variability in Stratospheric Chlorine Chemistry

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Perchlorate (ClO4−) in polar ice preserves past chlorine oxidation chemistry; however, multi‐centennial Antarctic ClO4− records and the mechanisms controlling their variability remain poorly constrained. Here, we present the first 400‐year (1616−2016) ClO4− record from an Antarctic ice core, revealing two regimes separated around 1980.

Wildfire Smoke Along Colorado's Front Range in 2020: An Evaluation of PM2.5 Monitor Spacing and Smoke Forecasts

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The 2020 wildfires caused widespread elevated fine particulate matter (PM2.5) concentrations across the western U.S. The Colorado Front Range experienced multiple smoke episodes from nearby fires and fires hundreds of kilometers away. Multiple days (88 total) with elevated PM2.5 along the Front Range occurred in 2020 between July and October ...

Evolutions of Non‐oxygenated Compounds in Sunlit Subarctic Thermokarst Pond Surface Waters

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract With global climate change, ground subsidence caused by permafrost thawing leads to the formation of thermokarst ponds, where organics from eroding permafrost accumulate in part as dissolved organic matter (DOM). Surface waters were collected from two subarctic thermokarst ponds with distinct characteristics: one palsa‐affected pond, which is ...
