Effect of stratosphere-troposphere exchange on the future tropospheric ozone trend [PDF]

Journal of Geophysical Research, 2003
This paper investigates the impact of circulation changes in a changed climate on the exchange of ozone between the stratosphere and the troposphere. We have identified an increase in the net transport of ozone into the troposphere in the future climate of 37%, although a decreased ozone lifetime means that the overall tropospheric burden decreases ...

Changes in Tropospheric Ozone Associated With Strong Earthquakes and Possible Mechanism

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The index of ozone anomaly (IOA) has been proposed to detect changes in tropospheric ozone associated with strong earthquakes. The tropospheric ozone prior and after the 2008 Wenchuan earthquake has been analyzed using IOA.

Surface matters: limitations of CALIPSO V3 aerosol typing in coastal regions [PDF]

Atmospheric Measurement Techniques, 2014
In the CALIPSO data analysis, surface type (land/ocean) is used to augment the aerosol characterization. However, this surface-dependent aerosol typing prohibits a correct classification of marine aerosol over land that is advected from ocean to land ...

Summertime free-tropospheric ozone pool over the eastern Mediterranean/Middle East [PDF]

Atmospheric Chemistry and Physics, 2014
Observations show that the Mediterranean troposphere is characterized by a marked enhancement in summertime ozone, with a maximum over the eastern Mediterranean.

Effects of stratospheric ozone recovery on photochemistry and ozone air quality in the troposphere [PDF]

Atmospheric Chemistry and Physics, 2014
There has been significant stratospheric ozone depletion since the late 1970s due to ozone-depleting substances (ODSs). With the implementation of the Montreal Protocol and its amendments and adjustments, stratospheric ozone is expected to recover ...

Tropospheric ozone trend over Beijing from 2002–2010: ozonesonde measurements and modeling analysis [PDF]

Atmospheric Chemistry and Physics, 2012
Using a combination of ozonesonde data and numerical simulations of the Chemical Lagrangian Model of the Stratosphere (CLaMS), the trend of tropospheric ozone (O₃) during 2002–2010 over Beijing was investigated.

Characteristics of tropospheric ozone depletion events in the Arctic spring: analysis of the ARCTAS, ARCPAC, and ARCIONS measurements and satellite BrO observations [PDF]

Atmospheric Chemistry and Physics, 2012
Arctic ozone depletion events (ODEs) are caused by halogen catalyzed ozone loss. In situ chemistry, advection of ozone-poor air mass, and vertical mixing in the lower troposphere are important factors affecting ODEs.

Evaluation of ACCMIP outgoing longwave radiation from tropospheric ozone using TES satellite observations [PDF]

Atmospheric Chemistry and Physics, 2013
We use simultaneous observations of tropospheric ozone and outgoing longwave radiation (OLR) sensitivity to tropospheric ozone from the Tropospheric Emission Spectrometer (TES) to evaluate model tropospheric ozone and its effect on OLR simulated by a ...

Drivers of the tropospheric ozone budget throughout the 21st century under the medium-high climate scenario RCP 6.0 [PDF]

Atmospheric Chemistry and Physics, 2015
Because tropospheric ozone is both a greenhouse gas and harmful air pollutant, it is important to understand how anthropogenic activities may influence its abundance and distribution through the 21st century.

Solar Ultraviolet Radiation in Pretoria and Its Relations to Aerosols and Tropospheric Ozone during the Biomass Burning Season

Atmosphere, 2021
Biomass burning has an impact on atmospheric composition as well as human health and wellbeing. In South Africa, the biomass burning season extends from July to October and affects the aerosol loading and tropospheric ozone concentrations which in turn ...
