Abstract
We present results fromtheOP3 campaign in Sabah during 2008 that allowus to study the impact of localemission changes over Borneo on atmospheric composition at the regional andwider scale. OP3 constituentdata provide an important constraint onmodel performance. Treatment of boundary layer processes is highlighted as an important area of model uncertainty.Model studies of land-use change confirm earlierwork, indicating that further changes to intensive oil palm agriculture in South EastAsia, and the tropics ingeneral, could have important impacts on air quality, with the biggest factor being the concomitantchanges in NO x emissions. With the model scenarios used here, local increases in ozone of around 50per cent could occur. We also report measurements of short-lived brominated compounds aroundSabah suggesting that oceanic (and, especially, coastal) emission sources dominate locally. The concentrationof bromine in short-lived halocarbons measured at the surface during OP3 amounted to about7 ppt, setting an upper limit on the amount of these species that can reach the lower stratosphere.
