SGER: Biomass Burning Aerosols in Southeast Asia: Smoke Impact Assessment (BASE-ASIA)

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对大气成分、辐射、水循环、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BASE-ASIA（东南亚生物质燃烧气溶胶：烟雾影响评估）项目的第一阶段在泰国部署马里兰大学飞机包。该项目包括收集现场和远程观测数据，并用数值模型进行分析，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。该飞机包将在2004年3月和4月的第一阶段试点研究期间提供一些气候和化学相关数量的机载观测。测量将在泰国国王航空气象飞机上进行，并将允许在曼谷和清迈附近地区对观察物种的垂直和水平结构进行量化。这项试验性研究将为今后在更大的地理区域进行研究和进行更多数量的观测奠定基础。将有重要的合作和利用nasa资助的研究部分，利用卫星远程观测和地面辐射测量。这项研究将为两位pi和一位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推广和机会。该项目将提供东南亚地区首个空中化学成分数据，由于东道国的安全考虑，目前还无法获得这些数据。这项试点研究将使社区更接近于了解这个快速发展地区排放的化学和气候影响。

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.
