Abstract. Regional estimates of arctic ecosystem [CO.sub.2] exchange are required because of the large soil carbon stocks located in arctic regions, the potentially large global-scale feedbacks associated with climate-change-induced alterations in arctic ecosystem C sequestration, and the substantial small-scale (1-10 [m.sup.2]) heterogeneity of arctic vegetation and hydrology. Because the majority of [CO.sub.2] flux data for arctic ecosystems are derived from plot-scale studies, a scaling routine that can provide reliable estimates of regional [CO.sub.2] flux is required. This study combined data collected from chamber measurements of [CO.sub.2] exchange, meteorology, ...
