Temporal and Spatial Patterns of the Interannual Variability of Stratospheric Ozone and Dynamics [PDF]

, 2004
This dissertation is a collection of empirical and modeling studies focusing on the interannual variability (IAV) of stratospheric ozone and the dynamics associated with that variability. Empirical analyses of the IAV of total column ozone in the tropics

On ozone trend detection: using coupled chemistry–climate simulations to investigate early signs of total column ozone recovery [PDF]

Atmospheric Chemistry and Physics, 2018
Total column ozone values from an ensemble of UM-UKCA model simulations are examined to investigate different definitions of progress on the road to ozone recovery. The impacts of modelled internal atmospheric variability are accounted for by applying

Spatial-temporal analysis of traffic-related ground level ozone [PDF]

, 2013
Prolonged exposure to elevated levels of ozone (O3) has been proven to adversely affect human health, agricultural crops and building materials. Therefore, ground level O3 is currently regarded as one of the most harmful air pollutants, and identified as

Radiative forcing since preindustrial times due to ozone change in the troposphere and the lower stratosphere [PDF]

, 2006
Changes in atmospheric ozone have occurred since the preindustrial era as a result of increasing anthropogenic emissions. Within ACCENT, a European Network of Excellence, ozone changes between 1850 and 2000 are assessed for the troposphere and the lower ...

A Study of the Vertical Distribution and Sub-Peaks of Ozone below 12 km over Wuyishan Region Based on Ozone Sounding in Winter

Atmosphere, 2022
An understanding of the vertical distribution of ozone is critical to assessing the ozone variabilities both in the stratosphere and the troposphere. We collected the profiles of atmospheric ozone partial pressure and ozone volume mixing ratio (VMR) by a

The sensitivity of stratospheric ozone changes through the 21st century to N₂O and CH₄ [PDF]

Atmospheric Chemistry and Physics, 2012
Through the 21st century, anthropogenic emissions of the greenhouse gases N2O and CH4 are projected to increase, thus increasing their atmospheric concentrations.

Effects of stratosphere-troposphere chemistry coupling on tropospheric ozone [PDF]

, 2010
[1] A new, computationally efficient coupled stratosphere-troposphere chemistry-climate model (S/T-CCM) has been developed based on three well-documented components: a 64-level general circulation model from the UK Met Office Unified Model, the ...

The direct fitting approach for total ozone column retrievals: a sensitivity study on GOME-2/MetOp-A measurements [PDF]

Atmospheric Measurement Techniques, 2015
We present a sensitivity study of the direct fitting approach to retrieve total ozone columns from the clear sky Global Ozone Monitoring Experiment 2/MetOp-A (GOME-2/MetOp-A) measurements between 325 and 335 nm in the period 2007–2010. The direct fitting

Trends and variability of total column ozone in the Third Pole

Frontiers in Climate, 2023
The Hindu Kush Himalaya and Tien Shan Mountain regions together are called the Third Pole (TP) of Earth, which encompasses ecologically fragile regions of 12 Asian countries. It is the highest mountain chain with the largest reserve of fresh ice mass on the planet outside the northern and southern polar regions.

Hemispheric differences in the return of midlatitude stratospheric ozone to historical levels [PDF]

, 2012
Chemistry-climate models (CCMs) project an earlier return of northern mid-latitude total column ozone to 1980 values compared to the southern mid-latitudes.
