U.S.-Russia Planning Visit: North Asian Sources of Greenhouse Gases; Collaborative Research using Ground- and Space-based Instruments.

这个项目为莫斯科大气物理研究所和俄罗斯叶卡捷琳堡乌拉尔国立大学的计划访问提供支持。美国首席和联合首席调查员是来自马里兰大学巴尔的摩分校的列昂尼德·尤尔加诺夫和威廉·麦克米兰。俄罗斯的同行是莫斯科的Evgeny Grechko博士和叶卡捷琳堡的Vyacheslav Zakharov博士。通过这一规划活动，美国参与者的目标是与俄罗斯同事建立长期的合作研究伙伴关系。他们将共同研究西伯利亚和俄罗斯西部对大气中重要气候气体（主要是CO和CH4，最终是CO2）浓度的影响。科学界的大多数人都认为，当前的气候变化极有可能与人类活动有关。然而，温室气体和地表温度的增加会引发额外的碳质气体的排放，从而放大最初的变化。这种由人类活动引发的自我支持的气候变化的概念目前在大气科学中是一个有争议的观点。在这方面，最重要的地理区域之一是西伯利亚北部，因为它拥有巨大的地表和地下碳储量。这种合作在本质上是互补的，因为它汇集了美国和俄罗斯在重要领域的专业知识，以解决一个及时的科学主题。

OISE 08-27507Leonid YurganovThis project provides support for a planning visit to the Institute of Atmospheric Physics in Moscow and Ural State University in Ekaterinburg, Russia. The U.S. principal and co-principal investigators are Leonid Yurganov and William McMillan from the University of Maryland Baltimore County. The Russian counterparts are Dr. Evgeny Grechko in Moscow and Dr. Vyacheslav Zakharov in Ekaterinburg.Through this planning activity, the US participants aim to establish a long-term collaborative research partnership with their Russian colleagues. Together they will study the influence of Siberia and Western Russia on the concentrations of climatically important gases (primarily, CO and CH4, and eventually, CO2) in the atmosphere. The majority of the scientific community agrees that current climate change is most likely connected with human activity. However, the increase of greenhouse gases and surface temperature can trigger emissions of additional carbonaceous gases that amplify the initial changes. This concept of a self-supporting climate change triggered by human activity is currently a controversial idea in the atmospheric sciences. One of the most important geographic regions in this respect is boreal Siberia due to its huge reserve of carbon on and below the surface. This collaboration is complementary in nature in that it brings together US and Russian expertise at important field sites to address a timely scientific topic.
