Spectroscopic measurements of atmospheric trace gases at Neumayer-Station, Antarctica
… research station Neumayer (70°S, 8°W). The measurements of the atmospheric trace gases ozone, NO2, OClO, BrO, IO and O4 were performed using a new UV/Vis spectrograph, developed within the scope of this work. The main intention of DOAS measurements in the Antarctic coastal region was to …

Development and Improvement of Spectroscopic Techniques for Atmospheric Composition Measurements from Ground and Space
… change requires a large body of observations and measurements of atmospheric composition. This requires the development of observational techniques and instrumentation, as well as modeling and methods for the correction of past measurements. Some of the more important atmospheric components that …

Summertime ozone pollution in China: Observations and Simulations
Ground-level ozone is a secondary atmospheric pollutant that damages human and vegetation health. The chemical production of ground-level ozone involves the photochemical reactions between nitrogen oxides (NOX = NO + NO2) and volatile organic compounds (VOCs). China is experiencing high levels of …

Observations of Tropospheric and Stratospheric Bromine Monoxide from Satellite : Analysis of Satellite Data derived from GOME for 1996-2001
… have been derived from satellite borne Global Ozone Monitoring Experiment measurements for the time period from 1996 to 2001 on a global scale. This data set has been analyzed under various aspects: two methods two achieve a separation of the stratospheric and tropospheric fractions of the …

Biofuels & atmospheric chemistry: what can a global model tell us about our future decisions?
… computer model, UKCA; the response of ozone turns out to depend on local chemical conditions. To evaluate the global model, I use data from the OP3 field campaign in Malaysia and compare it with output from the model chemical mechanism. The mechanism is able to reproduce NOx and ozone …

Tropospheric Ozone over the Middle East and Its Interannual Variability: An Integrated Analysis with Satellite Observations and a Global Chemical Transport Model
Tropospheric ozone is a major atmospheric pollutant and a greenhouse gas. Nevertheless, many processes influencing its spatio-temporal distribution are still poorly understood, mainly due to the lack of adequate observations. One such region is the Middle East, where ozone measurements are scant. …

Measurements and analysis of ozone production in Houston and Los Angeles
Ozone is a respiratory irritant that affects all groups of people, but can be of significant concern to young children, those with respiratory illnesses such as asthma, and the elderly. Repeated exposure can cause permanent lung damage. An estimated 123 million people in the Unites States live in …

Understanding Middle Atmospheric Composition Variability from the Solar Occultation for Ice Experiment Instrument and Other Datasets
… Clouds (PSCs), resulting in Antarctic ozone enhancement and a smaller ozone hole. The middle atmosphere is, thus, home to a diverse range of dynamics and chemistry, making it a critical subject that warrants attention from the science community. The continuous monitoring of the middle …
