Abstract

Eddy covariance data (FLUXNET) provide key insights into how carbon and water fluxes covary with climate and ecosystem states. Here we merge FLUXNET data with reanalyzed evaporative fraction and dynamic land cover to create monthly global carbon flux anomalies attributable to hydrologic change from 1948 to 2009. Changes in land cover had a relative influence of -1 relative to a global average sink of +2.8 Pg C yr^-1. Trends in hydroclimate-induced NEP anomalies exceeded the background mean sink in many regions. © 2011 by the American Geophysical Union.
