The Coweeta Hydrologic Laboratory (CHL) is a USDA Forest Service (FS) Experimental Forest, located in western North Carolina, in the southern Appalachian Mountains. Established in 1934, CHL has long-term data records that include climate, streamflow, stream and atmospheric chemistry, and vegetation in several small, experimentally-manipulated and reference watersheds. In addition to these long-term data, additional data associated with specific projects have been collected and are available through publications and electronic archives. Notably, CHL was a member of the National Science Foundation-funded Long-Term Ecological Research (LTER) program from 1980–2020, which resulted in significant scientific advances and rich data sets on the five core LTER research areas: primary productivity, population studies, movement of organic matter, movement of inorganic matter, and disturbance patterns. Here we provide a brief site description and history of the CHL, including descriptions of gauged watersheds and data archives.

Coweeta 水文实验室和 Coweeta 长期生态研究项目

Coweeta 水文实验室 (CHL) 是美国农业部林业局 (FS) 的一个实验森林，位于北卡罗来纳州西部阿巴拉契亚山脉南部。CHL 成立于 1934 年，拥有长期数据记录，包括气候、溪流、溪流和大气化学以及几个小型、实验操作和参考流域的植被。除了这些长期数据外，还收集了与特定项目相关的其他数据，并可通过出版物和电子档案获得。值得注意的是，CHL 是 1980 年至 2020 年美国国家科学基金会资助的长期生态研究 (LTER) 计划的成员，该计划在五个核心 LTER 研究领域取得了重大的科学进步和丰富的数据集：初级生产力、人口研究, 有机物的运动, 无机物的运动和扰动模式。在这里，我们提供了 CHL 的简要站点描述和历史，包括测量流域和数据档案的描述。
