【 摘 要 】

The primary goal of our research program, consistent with the goals of the U.S. Climate Change Science Program and funded by the terrestrial carbon processes (TCP) program of DOE, has been to improve understanding of changes in the distribution and cycling of carbon among the active land, ocean and atmosphere reservoirs, with particular emphasis on terrestrial ecosystems. Our approach is to systematically measure atmospheric CO(sub 2) to produce time series data essential to reveal temporal and spatial patterns. Additional measurements of the (sup 13)C/(sup 12)C isotopic ratio of CO(sub 2) provide a basis for distinguishing organic and inorganic processes. To pursue the significance of these patterns further, our research also involved interpretations of the observations by models, measurements of inorganic carbon in sea water, and of CO(sub 2) in air near growing land plants.
