USCCC was established in December 2003 in Beijing, P.R. China as a collaborative consortium between American and Chinese institutions that have interests in studying the role of managed ecosystems in the global carbon and water cycles. Representatives of two US institutions (Southern Global Change Program of USDA FS and University of Toledo) and seven Chinese institutions (Institute of Botany-CAS, Fudan University, Beijing Forestry University, Chinese Academy of Forestry, Nanjing University, and Meteorology Administration of China) participate in a planning workshop held in Beijing.
Eddy-covariance flux towers are the central infrastructure of all USCCC sites (total 18). Ten towers have been installed: three flux towers in coastal wetlands in Shanghai (FU), one tower in a young popular plantation in Beijing (BFU), two in forested wetlands (CAF), and four towers in four contrasting ecosystems in northeastern China (MAC). The remaining towers will be completed before 2005 growing season. A webpage housing other site information (e.g., vegetation, soil, climate, respiration, stable isotope analysis) are under construction by each of USCCC member.

MISSION:To facilitate a better understanding of the environmental factors influencing the rate and magnitude of carbon sequestration and water cycling across a range of ecosystems and climatic gradients with the use of mutually agreed upon measurement protocols and equipment, and through a collaborated network of data sharing and analysis.

The team agreed to propose a decentralized database management plan -- each institution will independently manage their data. The data will be open to all the partitioning members through project WebPages with permission of the institution. The committee strongly encourages its members to make their data as available as possible. USCCC will adopt the data sharing policy of Long-Term Ecological Research Networks (http://lternet.edu/data/netpolicy.html) for our future research. USCCC is governed by a steering committee:
The steering committee is responsible for
1)Formulating study objectives and research questions through its annual meetings;
2)Establishing and implementing field instrumentation, data collection, and other sampling methods;
3) Practical solutions for data quality assurance (QA) and quality control (QC), and data storage and dissemination;
4) Collaborative data analysis and compilation with the same metadata structure;
5) Forming consensus on research results for publications;6) Determining authorship and approve papers prior to journal
submission; and 7) Settling any problems or disputes that may arise within or
between sites and members.
