Cirrus cloud mimic surfaces in the laboratory: organic acids, bases and NOx heterogenous reactions

Obiettivo

It is proposed to investigate the mechanisms of heterogeneous reactions taking place between the important tropospheric pollutants, NO2, NO and NH3 and certain simple carboxylic acids on water-ice surfaces. The systems employed will be relevant to the ch aracterization of \"missing\" atmospheric chemistry, which has been suggested to be driven by cirrus cloud particulates. The core methodologies involved are based upon the successful water-ice, thin-film FT-RAIR studies previously performed in Professor Sodeau\'s laboratory. The experiments will be augmented by the complementary expertise possessed by Dr Hellebust to characterise ice surfaces and their catalytic activity by a variety of non-spectroscopic methods. Appropriate theoretical and empirical thermodynamic models will be used to consolidate the experimental results. All output information obtained will be made available to atmospheric modellers in order to improve our understanding of proposed sinks for the carboxylic acids and the release o f compounds such as HONO by heterogeneous processes currently assessed to be important but with little confirmatory experimental proof
