Natural and anthropogenic emissions from Southeast Asia and the maritime continent exert an important influence on atmospheric composition, climate and air quality. Changes in climate will most likely lead to changed emissions from the terrestrial and marine biospheres. In addition, emissions of air pollutants from Southeast Asia are driven by strong industrial growth and development, a trend likely to continue into the foreseeable future. Understanding these processes and their impacts is a crucial chemistry/climate question. Our aim is to improve quantitative understanding of the atmospheric impacts, on a range of spatial (from local to global) and temporal (from days to years) scales, of emissions of short-lived halocarbons and hydrocarbons in SE Asia and the maritime continent. We propose to establish a climatology of atmospheric concentrations of natural and anthropogenic halocarbons in the tropical boundary layer at five ground stations in Taiwan, Malaysia, Northern Australia and New Zealand from 2008 to 2011. Shorter-term measurements with a roving instrument will be made during research cruises and at other existing sites used by our colleagues at the University of Malaya. In collaboration with marine biologists we will investigate the factors influencing emissions and concentrations under a range of climate conditions. In a second phase, we will measure a range of hydrocarbons at the tropical sites. These measurements will then be used with numerical models to test and improve modelled emission estimates and to investigate their impact on tropospheric oxidative capacity, air quality and regional and global climate.

来自东南亚和海洋大陆的自然和人为排放对大气成分，气候和空气质量产生了重要影响。气候变化很可能导致陆地和海洋生物圈的排放变化。此外，来自东南亚的空气污染物的排放是由强劲的工业增长和发展驱动的，这种趋势很可能持续到可预见的未来。了解这些过程及其影响是一个至关重要的化学/气候问题。我们的目的是提高对大气影响的定量理解，对SE亚洲和海上大陆的短暂寿命盐和液压发射的一系列空间（从局部到全球）和时间范围（从几天到几年）的范围。我们建议在2008年台湾，马来西亚，北部澳大利亚和新西兰的五个地面站的热带边界层中建立大气浓度的天然和人为卤代碳的气候。与海洋生物学家合作，我们将研究影响一系列气候条件下的排放和浓度的因素。在第二阶段，我们将测量热带部位的一系列烃。然后，这些测量将与数值模型一起使用，以测试和改善建模的排放估计，并研究其对对流层氧化能力，空气质量以及区域和全球气候的影响。
