AB: FLUXNET is an internationally coordinated global network of long-term micrometeorological flux measurement sites that focus on measuring and interpreting the land-atmosphere exchanges of carbon dioxide, water vapor, and energy. The FLUXNET Data and Information System compiles flux data and related site characteristics data from regional flux networks from around the world for modeling the carbon cycle, analyzing the analysis of the controls on carbon, water, and energy fluxes, and validating remote sensing products. Flux data are being used to evaluate ecosystem model outputs and to validate remote sensing products, such as the photosynthesis product derived from the MODIS sensor on the Terra and Aqua satellites. Comparison of information from multiple types of local and regional studies is needed for understanding the dynamics of ecosystem-atmosphere carbon dioxide exchange and for extrapolating site studies to larger-scale products derived from remote sensing or global-scale modeling. We will demonstrate data products and tools for facilitating acquisition and intercomparison of the flux data, model output, and remote sensing data.
