Modeling atmospheric effects of the September 1859 Solar Flare [PDF]

, 2006
We have modeled atmospheric effects, especially ozone depletion, due to a solar proton event which probably accompanied the extreme magnetic storm of 1-2 September 1859. We use an inferred proton fluence for this event as estimated from nitrate levels in

Impact of future nitrous oxide and carbon dioxide emissions on the stratospheric ozone layer

Environmental Research Letters, 2015
The atmospheric levels of human-produced chlorocarbons and bromocarbons are projected to make only small contributions to ozone depletion by 2100. Increases in carbon dioxide (CO _2 ) and nitrous oxide (N _2 O) will become increasingly important in ...

Evolution of total column ozone prior to the era of ozone depletion

Frontiers in Earth Science, 2023
Total column ozone has been monitored for almost a century. The focus of most research studies over the last 40 years was on the era of ozone depletion and the detection of signs of recovery.

Ozone Depletion from Nearby Supernovae [PDF]

, 2002
Estimates made in the 1970's indicated that a supernova occurring within tens of parsecs of Earth could have significant effects on the ozone layer. Since that time, improved tools for detailed modeling of atmospheric chemistry have been developed to ...

Ozone Depletion Modulated by Arctic Polar Stratospheric Cloud Types

Geophysical Research Letters
Polar Stratospheric Clouds (PSCs) act as a reaction interface for polar stratospheric ozone depletion. In this study, we analyze the distribution characters of Arctic PSCs from 2006/2007 to 2020/2021, and investigate the impact of PSCs on ozone depletion

The Relationship between Polar Vortex and Ozone Depletion in the Antarctic Stratosphere during the Period 1979–2016

Advances in Meteorology, 2017
As the most prominent feature of the polar stratosphere, polar vortex results in widespread changes in the climate system, especially in the ozone variation.

Observations of ozone depletion events in a Finnish boreal forest [PDF]

Atmospheric Chemistry and Physics, 2018
We investigated the concentrations and vertical profiles of ozone over a 20-year period (1996–2016) at the SMEAR II station in southern Finland. Our results showed that the typical daily median ozone concentrations were in the range of 20–50 ppb with ...

ozone depletion

, 2014
The ozone layer is a belt of naturally occurring ozone gas that sits 9.3 to 18.6 miles (15 to 30 kilometers) above Earth and serves as a shield from the harmful ultraviolet B radiation emitted by the sun.

Rethinking reactive halogen budgets in the midlatitude lower stratosphere [PDF]

, 1999
Current stratospheric models have difficulties in fully explaining the observed midlatitude ozone depletion in the lowermost stratosphere, particularly near the tropopause.

Relationship Between Emissions of Human Activities and Ozone Layer Depletion [PDF]

, 2015
Ozone depletion always holds an importance being a protective shield to humans and environment as well. Human activities and man-made substances are playing major role to this depletion which is increasing day by day.
