RCN: Chequamegon Ecosystem-Atmosphere Study (ChEAS)

北方温带森林与大气之间的相互作用是契瓜密贡生态系统-大气研究（ChEAS）的重点。 ChEAS科学家正在研究北方威斯康星州的森林，以了解森林-大气系统的碳和水循环及其在地球气候系统中的作用。 最终目标是了解北方森林-大气系统将如何应对温室气体增加、土地使用变化和自然气候变化。 对碳和水循环有贡献的成分从土壤细菌或树叶孔隙的大小到急流的全球循环。 有些过程，如光合作用，随着积云的推移而变化，而其他过程，如森林演替，则对持续数十年甚至数百年的气候模式做出反应。 没有任何一种科学方法能够涵盖如此巨大的时间、空间和专业知识。 ChEAS研究合作网络为来自大气科学，生态学和水文学等各种学科的学生，教师和研究科学家以及机构提供资金，以交换数据，人员和科学理解。 这种信息交流将加速我们对地球气候的森林-大气组成部分的了解，并将有助于培养新一代的地球系统科学家。

Interaction between northern temperate forests and the atmosphere is the focus of the Chequamegon Ecosystem-Atmosphere Study (ChEAS). The ChEAS scientists are studying forests of northern Wisconsin to understand the carbon and water cycles of the forest-atmosphere system and their role in the earth's climate system. The ultimate goal is to learn how the northern forest-atmosphere system will respond to increases in greenhouse gases, land-use change, and natural climate variations. The components that contribute to the carbon and water cycles range from the size of a soil bacteria or leaf pore to the global circulation of the jet stream. Some processes, like photosynthesis, vary from one minute to the next with the passing of cumulus clouds, while others, such as forest succession, respond to climate patterns that persist over decades or even centuries. No single scientific method can encompass these vast scales of time, space, and disciplinary expertise. The ChEAS research collaboration network provides funds for students, faculty and research scientists from a wide variety of disciplines, including atmospheric science, ecology and hydrology, and institutions to exchange data, personnel, and scientific understanding. This exchange of information will accelerate our understanding of the forest-atmosphere component of the earth's climate and will help to train a new generation of earth system scientists.
