Project Description
The AmeriFlux Program is a network of CO2 flux measurement sites
throughout North and Central America. The AmeriFlux network is
intended to address complex issues relating to the global carbon cycle
by contributing to the understanding of factors that regulate rates of
uptake and net sequestration of CO2 by major biomes. The AmeriFlux is
a cooperative program with funding from a number of federal agencies
including Department of Energy (DOE), Department of Commerce/NOAA,
U.S. Department of Agriculture (USDA) Forest Service, NASA, and the
National Science Foundation (NSF).

The challenges for AmeriFlux are to; (1) extend surface-atmosphere CO2
flux studies in the spatial domain, producing a continental-scale data
base for evaluating the capacity of the terrestrial biosphere to
sequester carbon, (2) understand the analogous phenomena in a broad
range of major ecosystem types of potential importance in the global
carbon budget, (3) extend studies in the temporal domain to define the
impact of climate variation and climate change on carbon exchange
between the atmosphere and major biomes at decadal time scales, and,
(4) contribute to a global data base needed for global carbon cycle
model testing and validation. [from the AmeriFlux Science Plan]
