Description: Das Projekt "Measurement of Nitrous Acid during OASIS 2009 in Barrow (Alaska)" wird vom Umweltbundesamt gefördert und von Universität Wuppertal, Fachgruppe Chemie und Biologie, Arbeitsgruppe Physikalische und Theoretische Chemie durchgeführt. Nitrous acid (HONO) is an important source of the OH radical, the 'detergent of the atmosphere'. Unexpected high HONO concentrations were observed in polar region, which are still controversial under discussion. Thus, HONO was measured in Barrow in spring 2009 by an ultra-sensitive instrument, which was successfully validated against the well accepted DOAS technique even under complex conditions. The contribution of HONO to the oxidation capacity of the atmosphere will be quantified and potential sources will be identified.
