Paper Abstract

Potential multi-path spectroscopic differential absorption systems for the measurement of trace gases in the atmosphere are presented. Recommendations are made for system designs to be used for tomographic differential optical absorption spectroscopy (DOAS) measurements. The difficulties in producing multiple simultaneous beams from a single artificial light source are discussed, while the need for further tomographic resolution information is highlighted. An innovative prototype scanning-DOAS system is presented. The system is designed to generate multiple sequential paths, without the need for bulky and expensive mechanical systems. The scanning DOAS system can easily be placed in an industrial production plant or in a street canyon for multiple direction monitoring. The scanning DOAS system is currently being tested at the Cork Institute of Technology (CIT).
