Potter, C, Klooster, S, Tan, P, Steinbach, M, Kumar, V, Genovese, V (2005). Variability in terrestrial carbon sinks over two decades: Part 2 - Eurasia. GLOBAL AND PLANETARY CHANGE, 49(4-Mar), 177-186.

Abstract
We have analyzed 17 yr (1982-1998) of net carbon flux predictions from a simulation model based on satellite observations of monthly vegetation cover. The NASA-CASA model was driven by vegetation cover properties derived from the Advanced Very High Resolution Radiometer and radiative transter algorithms that were developed for the Moderate Resolution Imaging Spectroradionicter (MODIS). We report that although the terrestrial ecosystem sink for atmospheric CO2 for the Eurasian region has been fairly consistent at between 0.3 and 0.6 Pg C per year since 1988, high interannual variability in net ecosystem production (NEP) fluxes can be readily identified at locations across the continent. Ten major areas of highest variability in NEP were detected: eastern Europe, the Iberian Peninsula, the Balkan states, Scandinavia, northern and western Russia, eastern Siberia, Mongolia and western China, and central India. Analysis of climate anomalies over this 17-yr time period suggests that variability in precipitation and surface solar irradiance could be associated with trends in carbon sink fluxes within such regions of high NEP variability.
