Funded Activity Summary

Atmospheric photochemistry - it's a lot more complicated than we thought. The project plans to develop a more accurate model of the changing atmosphere. The chemical composition of Earth’s atmosphere is changing because of anthropogenic activities. Predicting the consequences of this change requires accurate chemical models. The hydroxyl radical (OH) is the most important radical in the atmosphere, yet atmospheric models predict its concentration in forested regions to be about 10 times lower than measured. These models also predict the amount of organic acids to be lower than measured. This project hypothesises two new chemical processes to account for these discrepancies. Photo-isomerisation of carbonyls to enols is suggested to be a source of organic acids. Reaction of extraordinarily hot carbonyl photofragments with oxygen is hypothesised to be an important source of OH radicals.
