Global-scale gravity wave analysis methodology for the ESA Earth Explorer 11 candidate CAIRT [PDF]

Atmospheric Measurement Techniques
In the past, satellite climatologies of gravity waves (GWs) have initiated progress in their representation in global models. However, these could not provide the phase speed and direction distributions needed for a better understanding of the ...

Stratospheric Ozone and Health [PDF]

International Journal of Epidemiology, 1994
Stratospheric ozone is being depleted and ambient ultraviolet (UV) irradiance is probably increasing. While remedial steps have been taken through the Montreal protocols, at best it will take some 90 years for stratospheric ozone concentrations to return to the levels existing in the 1970s.The evidence that these changes may have harmful effects on ...

Stratospheric hydration and ice microphysics of a convective overshoot observed during the TPEx campaign over Sweden [PDF]

Atmospheric Chemistry and Physics
This study examines the cloud microphysical properties and trace gas signatures associated with a convective overshooting event observed during the TPEx (TropoPause composition gradients and mixing Experiment) campaign in June 2024 over Sweden.

Tropical troposphere to stratosphere transport of carbon monoxide and long-lived trace species in the Chemical Lagrangian Model of the Stratosphere (CLaMS)

, 2014
. Variations in the mixing ratio of trace gases of tropospheric origin entering the stratosphere in the tropics are of interest for assessing both troposphere to stratosphere transport fluxes in the tropics and the impact of these transport fluxes on the

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 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

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 ...
