The stratosphere

open access: yesPhilosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2002
The stratosphere is that part of the atmosphere which lies between ca. 10 and 50 km above the surface of the Earth and which contains the ozone layer. It is the seat of much interesting behaviour in terms of dynamics, radiation and chemistry, now revealed in detail by observations from modern space instruments, but still not completely understood ...

Tuning of a convective gravity wave source scheme based on HIRDLS observations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Convection as one dominant source of atmospheric gravity waves (GWs) has been the focus of investigation over recent years. However, its spatial and temporal forcing scales are not well known.

100 Years of Progress in Understanding the Stratosphere and Mesosphere

open access: yesMeteorological Monographs, 2019
The stratosphere contains ~17% of Earth’s atmospheric mass, but its existence was unknown until 1902. In the following decades our knowledge grew gradually as more observations of the stratosphere were made.

Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA) scientific objectives [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
The upper troposphere/lower stratosphere (UTLS) represents an important part of the climate system. Even small changes in the composition and dynamic structure of this region have significant radiative effects.

How robust are stratospheric age of air trends from different reanalyses? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
An accelerating Brewer–Dobson circulation (BDC) is a robust signal of climate change in model predictions but has been questioned by trace gas observations.

Seasonal Evolution of Stratosphere‐Troposphere Coupling in the Southern Hemisphere and Implications for the Predictability of Surface Climate

open access: yesJournal of Geophysical Research - Atmospheres, 2018
Stratosphere‐troposphere coupling in the Southern Hemisphere (SH) polar vortex is an important dynamical process that provides predictability of the tropospheric Southern Annular Mode (SAM) and its associated surface impacts.

Identifying orographic gravity waves in 3D observations via backward ray tracing [PDF]

open access: yesAtmospheric Chemistry and Physics
Atmospheric gravity waves (GWs) generated by orography, commonly referred to as mountain waves (MWs), play a key role in driving atmospheric circulation and in modulating phenomena such as sudden stratospheric warmings (SSWs). Their contribution, however,

Pollution of the Stratosphere

open access: yesEnvironmental Conservation, 1974
Ozone in the stratosphere is vital to life on Earth. Yet it is chemically unstable and is susceptible to catalytic destruction from a long list of chemical substances, including NOX, HOX, CIOX, and metal oxides. In the stratosphere, these catalysts can be very active in ozone destruction, even when present at only one part of catalyst per 10,000 of ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...
