Understanding global teleconnections of climate to regional model estimates of Amazon ecosystem carbon fluxes
Abstract We have investigated global teleconnections of climate to regional satellite‐driven observations for prediction of Amazon ecosystem production, in the form of monthly estimates of net carbon exchange over the period 1982–1998 from the NASA–CASA (Carnegie–Ames–Stanford) biosphere model.
