Abstract
Tomographic-DOAS: from sensing to visualisation of urban street canyon pollutants S. O'Driscoll & N. J. Smith Environmental Monitoring & Space Science Group, Dept. of Applied Physics & Instrumentation, Cork Institute of Technology, Ireland. Abstract With over 75% of Europeans living and working in urbanised areas the quality of air in this environment is of extreme importance, influencing directly the health and well being of a significant proportion of the continent's population as well as impacting on the greater ecosystem. A microenvironment of particular interest is the street canyon where the spatial and temporal characteristics of pollutants are known to be complex, resulting from airflow patterns that transport and disperse the pollutants. Measurement of pollutants exhibiting such spatial and temporal variability will require new sensing approaches with high data quality standards. We discuss the use of Tomographic-DOAS (Differential Optical Absorption Spectroscopy) for the visualisatio
