Stratospheric Aircraft: Impact on the Stratosphere?
, 1992 The steady-state distribution of natural stratospheric ozone is primarily maintained through production by ultraviolet photolysis of molecular oxygen, destruction by a catalytic cycle involving nitrogen oxides (NO{sub x}), and relocation by air motions within the stratosphere.

Impact of Sudden Stratospheric Warmings on the Stratosphere-to-Troposphere Transport of Ozone
Geophysical Research LettersAbstract Sudden stratospheric warmings (SSWs) can significantly impact tropospheric weather systems. Previous studies suggest that SSWs may also influence stratosphere‐to‐troposphere transport (STT), but their spatial and temporal distribution and mechanisms are not fully understood.

Beyond the Biosphere: Decoding Bacterial Strategies at the Edge of Space
Journal of Pure and Applied MicrobiologyMicroorganisms exhibit remarkable phenotypic plasticity in extreme environments, including the stratosphere. This domain poses significant challenges such as almost zero gravity and a pronounced deviation from the typical physical forces experienced by ...

Geoscience Data Journal, Volume 13, Issue 3, July 2026.When a nuclear weapon is detonated in a region with sufficient fuel loading, the resulting firestorm can lift soot into the stratosphere, where it disperses globally over a few weeks. The soot, or black carbon, blocks sunlight, decreasing temperature and precipitation and depleting ozone.

International Journal of Chemical Kinetics, Volume 58, Issue 7, Page 396-406, July 2026.ABSTRACT The atmospheric chemistry of 1,4‐difluorobutane (CFH2CH2CH2CFH2) was investigated through a kinetic and mechanistic study of the reaction with chlorine (Cl) atoms and hydroxyl (OH) radicals. Using Fourier transform infrared (FTIR) spectroscopy and relative rate methods, the rate constants (k) for the reactions were determined at 298 ± 2 K as k(

Methane Emissions Offsetting With Temporary Carbon Sinks
GCB Bioenergy, Volume 18, Issue 7, July 2026.A time‐explicit framework based on atmospheric impulse–response functions quantifies the CO2 removal required to offset methane warming within 20 years. Constant, variable, and increasing carbon sinks each demand different removal masses, demonstrating that sink timing—not just permanence—determines the climate value of temporary carbon storage ...

Causal Impact of ENSO on Future Ozone Concentrations and Transport in the Tropical Tropopause Layer
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.Abstract Alterations in the tropopause are recognized as key signals of anthropogenic climate change and further understanding of the major drivers of future changes in the tropical tropopause layer (TTL) is crucial. Nevertheless, the causal effects of the El Niño‐Southern Oscillation (ENSO) on TTL remain elusive, particularly in a future warming ...

Influence of Observational Temperature Data Sets on ECS and TCR Estimates
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Uncertainties in estimates of Equilibrium Climate Sensitivity (ECS) and Transient Climate Response (TCR) are influenced by observational temperature data sets. Variability exists not just among the data products, but also within the creation of each one.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Parameterizing boundary layer turbulence in Earth System Models (ESMs) introduces a key source of uncertainty. Here, we explore the impact of implementing a prognostic formulation (PMF) for momentum flux, which permits countergradient (CG) fluxes.
