我们展示了 2008 年沙巴 OP3 活动的结果，使我们能够研究婆罗洲当地排放变化对区域和更广泛范围内大气成分的影响。 OP3 成分数据对模型性能提供了重要的约束。边界层过程的处理被强调为模型不确定性的一个重要领域。土地利用变化的模型研究证实了早期的工作，表明东南亚和整个热带地区集约化油棕农业的进一步变化可能对空气质量产生重要影响，其中最大的因素是随之而来的氮氧化物排放量的变化。根据此处使用的模型情景，局部臭氧可能会增加 50% 左右。我们还报告了沙巴周围短期溴化物的测量结果，表明海洋（尤其是沿海）排放源在当地占主导地位。 OP3期间在地表测得的短寿命卤化碳中的溴浓度约为7 ppt，这为这些能够到达平流层下部的物质的数量设定了上限。
We present results from the OP3 campaign in Sabah during 2008 that allow us to study the impact of local emission changes over Borneo on atmospheric composition at the regional and wider scale. OP3 constituent data provide an important constraint on model performance. Treatment of boundary layer processes is highlighted as an important area of model uncertainty. Model studies of land-use change confirm earlier work, indicating that further changes to intensive oil palm agriculture in South East Asia, and the tropics in general, could have important impacts on air quality, with the biggest factor being the concomitant changes in NOx emissions. With the model scenarios used here, local increases in ozone of around 50 per cent could occur. We also report measurements of short-lived brominated compounds around Sabah suggesting that oceanic (and, especially, coastal) emission sources dominate locally. The concentration of bromine in short-lived halocarbons measured at the surface during OP3 amounted to about 7 ppt, setting an upper limit on the amount of these species that can reach the lower stratosphere.
