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

OISE 08- 27507 Leonid Yurganov该项目为计划访问俄罗斯莫斯科的大气物理研究所和叶卡捷琳堡的乌拉尔州立大学提供支持。美国的主要和共同主要研究人员是来自马里兰州巴尔的摩县大学的Leonid Yurganov和William McMillan。 俄罗斯同行是莫斯科的Evgeny Grechko博士和叶卡捷琳堡的Vyacheslav Zakharov博士。通过这项计划活动，美国参与者旨在与俄罗斯同行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气候重要气体（主要是CO和CH 4，最终是CO2）浓度的影响。 大多数科学界人士认为，目前的气候变化很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想法。 在这方面，最重要的地理区域之一是西伯利亚北部，因为它在地表和地表下拥有巨大的碳储量。 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实地的专业知识，以解决一个及时的科学课题。

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.
