Chlorophyll index and photosynthetic carbon sequestration in Northern Eurasia

Based on physiological and biochemical evidence, the chlorophyll index of terrestrial vegetation cover of Northern Eurasia was proved a reliable tool for quantitative estimates of photosynthetic sequestration of atmospheric carbon. The photosynthetic carbon sequestration in the vegetation cover of Northern Eurasia, corrected for emissive carbon losses in the wood pool, was estimated at 4.7 Gt C/year. Accordingly, the refined estimate for net production in the vegetation ecosystem of Northern Eurasia approaches 1.3 Gt C/year.
