Remote sensing of atmospheric trace gases

TL;DRAbstract

This thesis describes work done in characterizing a number of important atmospheric trace gas species. There are two main components to this thesis. The first describes a 3 year measurement campaign of carbon dioxide, methane, nitrous oxide, carbonyl sulfide, carbon monoxide, nitrogen dioxide, hydrogen cyanide and formaldehyde total column amounts over Wollongong, in New South Wales, Australia (34.4°S, 150.9°E). The measurements were made by the examination of the intensity of characteristic absorption features observed in infrared spectra obtained by ground-based solar spectrometry. Carbon dioxide, nitrous oxide and hydrogen cyanide total column amounts increased over the campaign whilst a decrease was observed for carbon monoxide and formaldehyde. A larger than expected decrease in the carbonyl sulfide total column was also observed.\nThe second part of the thesis describes the investigation of the above methods suitability as a possible measurement tool for trace gases in the remote
