2010年度北极黄河站大气考察现场实施计划 项 目 名 称：北极苔原地区边界层物理过程和单颗粒黑碳气溶胶的观测研究 Title of project：Observational Research on the physical processes of boundary layer and single particle black carbon measurements over the tundra of the Arctic 负责人: 陆龙骅，卞林根 中国气象科学研究院 Principal Investigator: Prof. Lu Longhua and Bian lingen，Chinese Academy of Meteorological Sciences (CAMS) 执行人及其单位：孙俊英 中国气象科学研究院 Executor Organization: Dr. Sun Junying, Chinese Academy of Meteorological Sciences (CAMS) 研究目标： I Objective 在我国北极黄河站，开展北极苔原下垫面近地面物理过程的观测研究，获取该地近地面物理过程特征的第一手资料，为进一步开展有关研究（国际极地年IPY项目、自然科学基金项目），为各学科提供基本气象资料。 Observational Research on the boundary physics process of Arctic tundra region will be carried out at Chinese Yellow River station in Arctic, to achieve the first-hand data and provide basic meteorological information for related research (IPY project, NSSFC project and the others etc) and all related science fields. 通过对北极各类下垫面（陆地、冰雪、海面）与大气间的能量交换过程和特征参数的研究，进一步认识在大气-海洋-陆地耦合气候系统中北极边界层能量交换等物理过程，认识北极影响全球大气环流及我国天气气候的机理, 为发展我国高精度、高分辨率的海陆气相互作用的气候系统模式，提高我国短期气候预测能力，提供有关北极近地面物理过程的参考依据。 By studying the energy exchange process between all kinds of boundary layers (land, snow cover, sea) and atmosphere and their characteristic parameters, we understand more about the energy exchange process of Arctic boundary layer in the climate system coupled with Atmosphere-Sea-Land, understand more about the mechanism through which Arctic affect the global atmosphere circulation and weather and climate in our country. Besides these, more reference frame for the Arctic boundary physics process will be offered, which might enhance the development of high-precision and high-resolution coupled climate system model of China and improve our predictive capacity of short-term climate in China. 在我国北极黄河站，开展单颗粒黑碳气溶胶的在线观测，了解站区夏季黑碳浓度水平以及混合状态。 Single particle soot measurements will be carried out using single particle soot photometer at Yellow River station during the summer campaign in order to understand the mas
