US-China Carbon Consortium(USCCC)

US-China Carbon Consortium(USCCC)

• A multi-institutional effort on studying carbon
  and water cycles of managed ecosystems in eastern
  USA China

2
History
The USCCC was established on December 16, 2003 in
Beijing, P.R. China as a collaborative consortium
between American and Chinese institutions who
have common interests in studying the role of
managed ecosystems in the global carbon and water
cycles. 
3
Mission
The USCCC mission is 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 manor of
data sharing and analysis.
4
Objective
Our overall goal is to develop a suite of study
sites sponsored by the partner institutions in
hope that data and results will be shared so that
synthesis can be generated at broader spatial
scales to assess the importance of human
influences on carbon and water fluxes in a
changing climate.

Committee

• Co-Chair
• Dr. Xingguo Han, IB-CAS (China)
• Dr. Steve McNulty, SGCP-USDA (USA)
• Principal Scientist
• Dr. Jiquan Chen, Univ of Toledo
• Coordinator
• Dr. Osbert Sun, IB-CAS
• Representatives of participating institutes
• Dr. Guanghui Lin, IB-CAS
• Dr. Bo Li, Fudan University
• Dr. Zhiqiang Zhang, Beijing Forestry Univ.
• Dr. Xudong Zhang, Chinese Academy of Forestry

The steering committee is responsible for
coordinating USCCC activities.  This includes 1)
the formulation of study objectives and research
questions through its annual meetings 2)
establishment and implementation of unified field
instrumentation, data collection, and other
sampling methods 3) coordinating 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 5) suggesting
authorships prior to journal submission and 6)
settling any problems or disputes that may arise
within or between sites and members.

Litter Fall Decomposition
Twenty seven hardmast plots (Acorn plots) were
randomly selected and litter falls will be
collected at number 2, 4, 6, 8 traps at each plot
every 3 months.
Twenty litter bags were buried for litter
decomposition and retrieve time intervals 1.5,
3, 6, 12, 24 months in each site

Image Processing

• A combination of direct measurements, remote
  sensing images, and ecosystem models
• USCCC is seeking for collaborative research from
  the RS and modeling community as no expertise
  exits within the group.

Data QA/QC, Management, and Sharing
USCCC adopted the data sharing policy of
Long-Term Ecological Research Networks (LTER,
http//lternet.edu/data/netpolicy.html) for our
future research.
30
Data QA/QC, Management, and Sharing

• A centralized data management dogma (e.g., of of
  Fluxnet and LTER) may not work for USCCC
• A decentralized data sharing and management with
  agreeable metadata is much better
• The concept of EcoNodes is under consideration.

31
EcoGrid client interactions

• Modes of interaction
• Client-server
• Fully distributed
• Peer-to-peer
• EcoGrid Registry
• Node discovery
• Service discovery
• Aggregation services
• Centralized access
• Reliability
• Data preservation

funded Dr. G. Lin ( IB-CAS, CAS,) to conduct
monthly measurements of stable oxygen and

of hydrological and climate research at global
scales at the following USCCC sites 1).
Xilinhot grassland research station site2).
Duolun site3). Kubiqi poplar plantation site4).
