AB: A simulation model (NASA-CASA) based on satellite observations of monthly vegetation cover from the moderate resolution imaging spectroradiometer (MODIS) was used to estimate monthly carbon fluxes in terrestrial ecosystems during 2001. For the terrestrial biosphere, predicted net ecosystem production (NEP) flux for atmospheric carbon dioxide was estimated as annual net sink of 3.6 Pg C. Our NASA-CASA model results for NEP in 2001 reflect observed climate patterns between and within major continental areas of the terrestrial biosphere. Above average temperatures were strongly associated with positive NEP (net sink fluxes) across the high latitude zones of eastern Canada and Eurasia. Positive NEP fluxes were also associated with the heavy rainfall reported in eastern Europe, Siberia, Australia, West Africa, and southern Africa. Negative NEP (net source fluxes) were associated with severe droughts reported in south Asia, eastern Africa, northern China, and northern and eastern coastal South America.
