After decades of depletion in the 20th century, near-global ozone now shows clear signs of
recovery in the upper stratosphere. The ozone column, however, has remained largely …

Abstract The NASA Goddard Earth Observing System (GEOS) Composition Forecast (GEOS‐
CF) provides recent estimates and 5‐day forecasts of atmospheric composition to the public …

Résumé Thanks to the Montreal Protocol, the stratospheric concentrations of ozone-
depleting chlorine and bromine have been declining since their peak in the late 1990s …

Abstract The Stratospheric Aerosol and Gas Experiment III on the International Space
Station (SAGE III/ISS) was launched on 19 February 2017 and began routine operation in …

The SPARC Data Initiative (SPARC, 2017) performed the first comprehensive assessment of
currently available stratospheric composition measurements obtained from an international …

This study focuses on responses of mesospheric water vapor (H2O) to the solar cycle flux at
Lyman‐α wavelength and to dynamical forcings according to the multivariate El …

We developed a set of solar zenith angle, latitude-and altitude-dependent scaling factors to
account for the diurnal variability in ozone (O 3) and nitrogen dioxide (NO 2) when …

The solar cycle (SC) stratospheric ozone response is thought to influence surface weather
and climate. To understand the chain of processes and ensure climate models adequately …

Observing stratospheric ozone is essential to assess whether the Montreal Protocol has
succeeded in saving the ozone layer by banning ozone depleting substances. Recent …

Reliable ozone trends after 2000 are essential to detect early ozone recovery. However, the
long-term ground-based and satellite ozone profile trends reported in the literature show a …
