Southeast Asia is a rapidly developing region that has very polluted air due to biomass burning and inefficient, low technology fossil fuel combustion. In addition to the impact on the local air quality, these gaseous and particulate pollutants my have regional and global influences on atmospheric composition, radiation, the hydrological cycle, biogeochemical cycles and biodiversity. This project involves the deployment of the University of Maryland aircraft package in Thailand during the first phase of the multi-disciplinary, multi-institutional, multi-agency supported BASE-ASIA (Biomass burning Aerosols in Southeast Asia: Smoke Impact Assessment) project. This program involves the collection of in situ and remote observational data, and analysis with numerical models to address questions related to the type, frequency, intensity and geographical extent of key pollutant emissions in the southeastern Asia region, and to attempt to understand how these pollutants impact regional air quality, radiation, and weather. The aircraft package will provide airborne observations of a number of climate and chemistry related quantities during the first phase pilot study in March and April, 2004. Measurements will be conducted aboard a Thai King Air weather aircraft, and will allow the vertical and horizontal structure of the observed species to be quantified in the regions near Bangkok and Chiang Mai. This pilot study will set the stage for future studies of a larger geographical region and with observations of more quantities. There will be significant collaboration and leveraging of the NASA-funded part of the study making use of satellite remote observations and surface radiation measurements.This study will provide support and research experience for the two PIs, one graduate student, and there will be significant outreach and opportunities for Asian students and scientists. The project will provide the first airborne chemical composition data over Southeast Asia, data until now unavailable due to security concerns of host countries. This pilot study will move the community a step closer to understanding the chemical and climatic impacts of emissions from this rapidly developing region.

东南亚是一个快速发展的地区，由于生物质燃烧和低效、低技术的化石燃料燃烧，空气污染严重。除了对当地空气质量的影响外，这些气体和颗粒污染物还可能对大气成分、辐射、水文循环、生物地球化学循环和生物多样性产生区域和全球影响。该项目涉及在多学科、多机构、多机构支持的亚洲基地(东南亚生物质燃烧气雾剂：烟雾影响评估)项目的第一阶段在泰国部署马里兰大学的一揽子飞机。该方案包括收集现场和远程观测数据，并使用数值模式进行分析，以解决与东南亚地区主要污染物排放的类型、频率、强度和地理范围有关的问题，并试图了解这些污染物如何影响区域空气质量、辐射和天气。该飞机组合将在2004年3月和4月的第一阶段试点研究期间提供一些与气候和化学相关的空中观测。测量将在泰国国王航空公司的一架气象飞机上进行，并将允许量化曼谷和清迈附近地区观察到的物种的垂直和水平结构。这项初步研究将为今后更大范围的地理区域研究和更多数量的观测奠定基础。这项研究将利用卫星遥感观测和表面辐射测量，对NASA资助的部分进行重要的合作和利用。这项研究将为两名PI，一名研究生提供支持和研究经验，并将为亚洲学生和科学家提供重要的拓展和机会。该项目将提供东南亚地区的第一个空中化学成分数据，由于东道国的安全担忧，这些数据到目前为止还无法获得。这项初步研究将使社区更接近了解这一快速发展地区排放的化学和气候影响。
