Thermospheric Energy and Heating Due To Upward Propagating and in Situ Generated Tides During Solar Cycle 24

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We investigate vertical and horizontal energy transport and associated heating in the thermosphere due to both upward propagating and in situ generated migrating and nonmigrating diurnal and semidiurnal tides over the solar cycle 24 (2009–2019).

Numerical Simulations of Sulfate Formation via the Diffusive Reaction Between Ca2+ in Volcanic Ash and SO2 Gas: Evaluation of SO2 Losses From Eruption Clouds During the 1991 Pinatubo Eruption

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Volcanic ash formed during explosive volcanism reacts with SO2 gas molecules in volcanic conduits and eruption clouds, resulting in the formation of CaSO4. When ash is removed from the eruption cloud, the SO2 gas molecule is scavenged from the eruption cloud. The CaSO4 growth is rate‐limited by Ca2+ diffusion at high temperatures.

Ozone Depletion Modulated by Arctic Polar Stratospheric Cloud Types

Geophysical Research Letters
Polar Stratospheric Clouds (PSCs) act as a reaction interface for polar stratospheric ozone depletion. In this study, we analyze the distribution characters of Arctic PSCs from 2006/2007 to 2020/2021, and investigate the impact of PSCs on ozone depletion

Upper-atmosphere Aerosols: Properties and Natural Cycles [PDF]

, 1992
The middle atmosphere is rich in its variety of particulate matter, which ranges from meteorite debris, to sulfate aerosols, to polar stratospheric ice clouds. Volcanic eruptions strongly perturb the stratospheric sulfate (Junge) layer.

Acidification Stimulates N2O Production by Oceanic Nitrifying Bacteria

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Recent studies have shown changes in the production rates of nitrous oxide (N2O) in aerobic seawater in response to ocean acidification (OA). Understanding how N2O production responds to OA is crucial because N2O is a strong greenhouse gas and stratospheric ozone‐depleting substance emitted from the ocean.

An assessment of an F2 or N2O4 atmospheric injection from an aborted space shuttle mission [PDF]

Assuming a linear relationship between the stratosphere loading of NOx and the magnitude of the ozone perturbation, the change in ozone expected to result from space shuttle ejection of N2O4 was calculated based on the ozone change that is predicted for ...

Incorporating Gas‐Phase Chemistry Into the Unified Forecast System (UFS) for Global Air Quality Applications

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract The Unified Forecast System (UFS) is a community‐based Earth modeling system designed to support operational forecasts at the National Oceanic and Atmospheric Administration (NOAA), while also facilitating the integration of research advances from the broader scientific community.

Climate Change, Air Quality, and Pollen Allergies—State of the Art and Recommendations for Research and Public Health

Allergy, Volume 81, Issue 3, Page 663-683, March 2026.
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,
