Nighttime ozone in the lower boundary layer: insights from 3-year tower-based measurements in South China and regional air quality modeling [PDF]

Atmospheric Chemistry and Physics, 2023
Nighttime ozone in the lower boundary layer regulates atmospheric chemistry and surface ozone air quality, but our understanding of its vertical structure and impact is largely limited by the extreme sparsity of direct measurements.

Ozone reservoir layers in a coastal environment – a case study in southern Taiwan [PDF]

Atmospheric Chemistry and Physics, 2010
The air layer between the nocturnal boundary layer and the top of the daily mixing layer in an ozone-polluted area is known to serve as an ozone reservoir since the ozone that is produced in the mixing layer on the preceding day is effectively preserved ...

Ozone concentration at various heights near the surface layer in Shenyang, Northeast China

Frontiers in Environmental Science, 2022
Ozone pollution has been growing in the recent decade, becoming a critical urban environmental issue in China. However, Shenyang’s near-surface ozone concentration (ground to 100 m altitude) is of grave concern.

Entrainment and Mixing of Transported Ozone Layers: Implications for Surface Air Quality in the Western U.S. [PDF]

EPJ Web of Conferences, 2020
Recently, two air quality campaigns were conducted in the southwestern United States to study the impact of transported ozone, stratospheric intrusions, and fire emissions on ground-level ozone concentrations.

Stratospheric ozone fluctuation and ultraviolet radiation over Serbia [PDF]

Nuclear Technology and Radiation Protection, 2011
Increased ultraviolet radiation potentially detrimental to health is a direct effect of the reduced ozone layer of the Earth’s atmosphere. Stratospheric ozone over the territory of Serbia and immediate surrounding depleted in the considered period of ...

Impact of the assimilation of ozone from the Tropospheric Emission Spectrometer on surface ozone across North America [PDF]

, 2009
We examine the impact of assimilating ozone observations from the Tropospheric Emission Spectrometer (TES) on North American surface ozone abundances in the GEOS-Chem model in August 2006.

Stratospheric dynamics modulates ozone layer response to molecular oxygen variations

Frontiers in Earth Science, 2023
Photolysis of molecular oxygen (O2) sustains the stratospheric ozone layer and is thereby protecting living organisms on Earth by absorbing harmful ultraviolet radiation.

A reanalysis of ozone on Mars from assimilation of SPICAM observations [PDF]

, 2018
We have assimilated for the first time SPICAM retrievals of total ozone into a Martian global circulation model to provide a global reanalysis of the ozone cycle.

Investigation of the Successive Ozone Episodes in the El Paso–Juarez Region in the Summer of 2017

Atmosphere, 2020
The adjacent cities of El Paso in Texas, USA, and Juarez in Mexico commonly experience pollution episodes, especially during the summer months. In the summer of 2017, successive high and low ozone episodes were observed. Aerosol backscattered data from a
