Title: Aspects of spatial and temporal aggregation in estimating regional carbon dioxide fluxes from temperate forest soils

Abstract

We examine the influence of aggregation errors on developing estimates of regional soil-CO{sub 2} flux from temperate forests. We find daily soil-CO{sub 2} fluxes to be more sensitive to changes in soil temperatures (Q{sub 10} = 3.08) than air temperatures (Q{sub 10} = 1.99). The direct use of mean monthly air temperatures with a daily flux model underestimates regional fluxes by approximately 4%. Temporal aggregation error varies with spatial resolution. Overall, our calibrated modeling approach reduces spatial aggregation error by 9.3% and temporal aggregation error by 15.5%. After minimizing spatial and temporal aggregation errors, mature temperate forest soils are estimated to contribute 12.9 Pg C yr{sup {minus}1} to the atmosphere as carbon dioxide. Georeferenced model estimates agree well with annual soil-CO{sub 2} fluxes measured during chamber studies in mature temperate forest stands around the globe. 75 refs., 8 figs., 5 tabs.
