Role of Future Climate Change, Air Pollution Control and Methane Mitigation in Driving Hydroxyl Radical (OH) and Methane Lifetime

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The hydroxyl radical (OH) determines the atmospheric lifetime of many pollutants like methane (CH4 ${\text{CH}}_{4}$). This study isolates climate change, air pollution control and CH4 ${\text{CH}}_{4}$ mitigation effects on OH concentrations ([OH]) and CH4 ${\text{CH}}_{4}$ lifetime, by analyzing Coupled Model Intercomparison Project Phase 6 (

Distinct Efficacy of Regional Methane Emissions in Affecting Global and Regional Concentrations: An Emission‐Driven CESM2 Modeling Study With Methane Tags

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The newly developed emission‐driven capability of CESM2 allows methane concentrations to be more realistically simulated based on emissions, transport, and atmospheric chemistry, rather than being prescribed as lower boundary conditions as in most previous global Earth system modeling studies.

Initial Atmospheric Waves Experiment (AWE) Imaging Analyses: Gravity Wave Sources, Temperatures, Pseudomomentum Fluxes, and Horizontal Wavenumber Spectra at the OH Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The NASA Atmospheric Waves Experiment (AWE) employs an OH imager that began measurements aboard the International Space Station (ISS) on 22 November 2023. The motivation for AWE was to quantify gravity wave (GW) responses to diverse sources and their influences extending into the mesosphere and higher altitudes.
