AmeriFlux Objectives<br />
Generally:<br />
• Establish an infrastructure for guiding, collecting,<br />
synthesizing, and disseminating long-term<br />
measurements of CO 2 , water, and energy exchange<br />
from a variety of ecosystems.<br />
• Collect critical new information to help define the<br />
current global CO 2 budget<br />
• Enable improved predictions of future<br />
concentrations of atmospheric CO 2<br />
• Enhance understanding of carbon fluxes, Net<br />
Ecosystem Production (NEP), and carbon<br />
sequestration in the terrestrial biosphere.<br />
Specifically:<br />
• Share data and the science plan.<br />
• Quantify magnitude of net annual CO 2 exchange in<br />
major ecosystem/biome types (natural and<br />
managed)<br />
• Determine response of CO 2 fluxes to changes in<br />
environmental factors and climate changes<br />
• Provide information on processes controlling CO 2<br />
flux and net ecosystem productivity<br />
• Provide site-specific calibration and verification data<br />
for process-based CO 2 flux models.<br />
• Address scaling issues (spatial and temporal).<br />
• Quality control and quality assure data collection.
