Evidence for a continuous decline in lower stratospheric ozone offsetting ozone layer recovery [PDF]
Atmospheric Chemistry and Physics, 2018 Ozone forms in the Earth's atmosphere from the photodissociation of molecular oxygen, primarily in the tropical stratosphere. It is then transported to the extratropics by the Brewer–Dobson circulation (BDC), forming a protective ozone layer around ...

Northern winter stratospheric temperature and ozone responses to ENSO inferred from an ensemble of Chemistry Climate Models [PDF]
, 2009 The connection between the El Ni˜no Southern Oscillation (ENSO) and the Northern polar stratosphere has been established from observations and atmospheric modeling. Here a systematic inter-comparison of the sensitivity of the modeled stratosphere to ENSO

The simulation of the Antarctic ozone hole by chemistry-climate models [PDF]
Atmospheric Chemistry and Physics, 2009 While chemistry-climate models are able to reproduce many characteristics of the global total column ozone field and its long-term evolution, they have fared less well in simulating the commonly used diagnostic of the area of the Antarctic ozone hole i.e.

Recent trends of the total column ozone: implications for the Mediterranean region
International Journal of Remote Sensing, 1995 Abstract The daily ozone column amounts during the 14-year period (1979–1992), which are inferred from measurements made with both the Total Ozone Mapping Spectrometer (TOMS) mounted on board the Nimbus-7 satellite have been used to study longitudinal trends at mid-latitudes.

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Atmospheric Chemistry and Physics, 2022 Abstract. The occurrence of tropospheric ozone depletion events (ODEs) in the Antarctic can be influenced by many factors, such as the total ozone column (TOC). In this study, we analyzed the observational data obtained from ground observation stations and used two numerical models (TUV and KINAL), to discover the relationship between the TOC and the ...

A global historical ozone data set and prominent features of stratospheric variability prior to 1979 [PDF]
Atmospheric Chemistry and Physics, 2013 We present a vertically resolved zonal mean monthly mean global ozone data set spanning the period 1901 to 2007, called HISTOZ.1.0. It is based on a new approach that combines information from an ensemble of chemistry climate model (CCM) simulations with

Onset of Stratospheric Ozone Recovery in the Antarctic Ozone Hole in Assimilated Daily Total Ozone Columns [PDF]
Journal of Geophysical Research: Atmospheres, 2017 AbstractIn this paper we evaluate the long‐term changes in ozone depletion within the Antarctic ozone hole using a 37 years (1979–2015) of daily ozone mass deficits (OMDs) derived from assimilated total ozone column data. For each year an “average daily OMD” is calculated over a 60 day preferential time period (day of year 220–280).
