Summary
Abstract: A large variety of nonmethane hydrocarbons (NMHCs) are found throughout the troposphere in varying concentrations. The reaction of a NMHC with the hydroxyl (OH) molecule causes atmospheric oxidation. Small whole dry air samples (2L) are collected annually (between 12 and 18 samples) from Arrival Heights (since 1990), dried using magnesium perchlorate and analysed to determine the mixing ratio of C2-C10 NMHC as a means of deducing atmospheric oxidation. Sample collection is aimed at the clean sector of the sky from the West through North to East, throughout the year.
