AB: We describe the development of a ground-based network for measurement of the total CO2 column (Total Carbon Column Observing Network - TCCON). These data are derived from analysis of near-IR solar spectra obtained with high spectral resolution using FTIR spectrometers. Observations are currently made at seven globally-distributed sites, and planned at several others. They have been evaluated against aircraft in situ profiles in Park Falls, Wisconsin, Darwin, Australia, and Los Angeles, California. We show how these observations constrain the strength of exchange of carbon between the surface and the atmosphere. Implications for current and future CO2 observations from space are described.
