An examination of chemistry and transport processes in the tropical lower stratosphere using observations of long-lived and short-lived compounds obtained during STRAT and POLARIS [PDF]
, 1999 A suite of compounds with a wide range of photochemical lifetimes (3 months to several decades) was measured in the tropical and midlatitude upper troposphere and lower stratosphere during the Stratospheric Tracers of Atmospheric Transport (STRAT ...

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

A linear CO chemistry parameterization in a chemistry-transport model: evaluation and application to data assimilation [PDF]
, 2010 This paper presents an evaluation of a new linear parameterization valid for the troposphere and the stratosphere, based on a first order approximation of the carbon monoxide (CO) continuity equation. This linear scheme (hereinafter noted LINCO) has been

A Method for Establishing a Station-Keeping, Stratospheric Platform for Astronomical Research
, 2015 During certain times of the year at middle and low latitudes, winds in the upper stratosphere move in nearly the opposite direction than the wind in the lower stratosphere. Here we present a method for maintaining a high-altitude balloon platform in near

Structural changes in the shallow and transition branch of the Brewer–Dobson circulation induced by El Niño [PDF]
Atmospheric Chemistry and Physics, 2019 The stratospheric Brewer–Dobson circulation (BDC) determines the transport and atmospheric lifetime of key radiatively active trace gases and further impacts surface climate through downward coupling.

Global analysis for periodic variations in gravity wave squared amplitudes and momentum fluxes in the middle atmosphere [PDF]
Annales Geophysicae, 2019 Atmospheric gravity waves (GWs) are an important coupling mechanism in the middle atmosphere. For instance, they provide a large part of the driving of long-period atmospheric oscillations such as the Quasi-Biennial Oscillation (QBO) and the semiannual ...

Tomographic reconstruction of atmospheric gravity wave parameters from airglow observations [PDF]
Atmospheric Measurement Techniques, 2017 Gravity waves (GWs) play an important role in the dynamics of the mesosphere and lower thermosphere (MLT). Therefore, global observations of GWs in the MLT region are of particular interest.

Correlated variability of upwelling and tracers near the tropical tropopause [PDF]
, 2012 Tropical upwelling should exert strong influence on temperatures and on tracers with large vertical gradients in the lower stratosphere. We test this behavior by comparing three upwelling estimates calculated from ERA‐Interim reanalysis data with ...
