Impact of Sudden Stratospheric Warmings on the Stratosphere-to-Troposphere Transport of Ozone

Geophysical Research Letters
not-yet-known not-yet-known not-yet-known unknown 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

Atmospheric Chemistry of CF3C(Cl)═CH2 (HCFO‐1233xf)

International Journal of Chemical Kinetics, Volume 58, Issue 11, Page 943-953, November 2026.
ABSTRACT 2‐chloro‐3,3,3‐trifluoropropene, CF3C(Cl)═CH2 (HCFO‐1233xf), is a volatile hydrochlorofluoroolefin, commonly used in industrial synthesis of other halogenated olefins. Kinetics and reaction mechanisms for the reactions of OH radicals, Cl atoms, and O3 with CF3C(Cl)═CH2 were investigated using FTIR/smog chamber studies in 700 Torr of air/N2 ...

Ultraviolet radiation lowers upper thermal limits in marine diatoms

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract Escalating ultraviolet radiation (UVR) and ocean warming are expected to interactively shape phytoplankton performance, yet their combined effects on diatom thermal plasticity remain poorly resolved. We quantified how UVR alters growth‐based thermal performance curves in three model marine diatoms grown across species‐specific temperature ...

Representation of tropical deep convection in atmospheric models - Part 1 : Meteorology and comparison with satellite observations [PDF]

, 2011
Fast convective transport in the tropics can efficiently redistribute water vapour and pollutants up to the upper troposphere. In this study we compare tropical convection characteristics for the year 2005 in a range of atmospheric models, including ...

Beyond the Biosphere: Decoding Bacterial Strategies at the Edge of Space

Journal of Pure and Applied Microbiology
Microorganisms 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 ...

Covalent Organic Frameworks in Smart Food Packaging: Advances, Challenges, and Future Prospects

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Food preservation challenges have positioned packaging as a rapidly evolving, innovation‐driven field, with smart packaging offering transformative solutions. Among advanced materials, covalent organic frameworks (COFs) have attracted growing attention due to their permanent porosity, structural tunability, high surface area, and chemical ...

Hyperinflation and High Inflation in Venezuela: Monetary or Exchange Rate Origin?

Kyklos, Volume 79, Issue 4, Page 1053-1077, November 2026.
ABSTRACT From 2018 to 2021, Venezuela experienced a period of intense hyperinflation. There are two hypotheses regarding the origin of such hyperinflation. The monetarist hypothesis attributes hyperinflation to excessive growth in the money supply, typically resulting from public deficits. Alternatively, the structuralist balance of payments hypothesis

Determination of the distribution of halocarbons in the tropical upper troposphere and stratosphere [PDF]

, 2008
The aim of this thesis was to investigate distributions of 32 volatile chlorinated and/or brominated halocarbons that are currently believed to be present in the tropical upper troposphere and stratosphere and to contribute to stratospheric ozone ...

Stratospheric Aerosol From Above: Laser‐Ablation Mass Spectrometer Samples Polar Vortex Air for the First Time

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract The JGR paper by Lawler et al. (2025, https://doi.org/10.1029/2025jd043530) marks a significant and historic first, the PALMS single‐particle chemical analysis sampling deep stratospheric Arctic vortex air for the first time. The analysis finds ∼90% of sulfate aerosol particles in the deepest stratosphere air (100–130 ppb N2O) are meteoric ...

Quantifying Nighttime Gravity Wave‐Driven Mesosphere‐Ionosphere Coupling Over CONUS Using NASA AWE Radiance and GNSS TEC Observations

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We present the first coordinated study of nighttime mesosphere‐ionosphere coupling over the continental United States (CONUS) from January through November 2024 using NASA Atmospheric Waves Experiment (AWE) airglow measurements near 87 km and GNSS Total Electron Content observations near 300 km.
