Patryk Wojtal: Nocturnal Measurements of HONO, NO2 and NO3 by Differential Optical Absorption
Dec 12, 2013, 1pm-1:45pm
You are invited to attend a public lecture.
Patryk Wojtal (Faculty of Graduate Studies, Graduate Program in Chemistry, Oral Examination Prospectus) a candidate for the degree of doctor of philosophy, will present the nocturnal measurements of HONO, NO2 and NO3 by differential optical absorption spectroscopy in polluted marine and urban atmospheres.
Abstract: Nitrogen oxides are ubiquitous throughout the lower atmosphere and significantly affect the chemistry of the atmosphere, air quality and climate. A dataset obtained using differential optical absorption spectroscopy (DOAS) was analyzed to quantify the NO3, HONO and NO2 concentrations at Saturna Island, and concentrations of N2O5 were calculated. Nocturnal measurements of NO3, NO2 and HONO were performed using active-DOAS at York University.
