Russian Terrestrial FCA: 1988–1992Average Annual Atmospheric Sink Strength -0.35± 0.10 (This Study, 2003) -0.15± 0.12 (Nilsson et al., 2000) Terrestrial Sink Strength [PgC yr-1] 7
Conclusions for 1990 Estimates • Modified systems view with respect to soils and inclusion of more detailed lateral and horizontal fluxes resulted in doubling the net terrestrial sink capacity. Combination of process based methods with inventories • The assessment of the atmospheric/terrestrial exchange is sensitive to small changes in surface and sub-surface fluxes • The uncertainties are substantially reduced • Underlining the need for thorough and full accounting including all fluxes IIASA Forestry Program 8

Conclusions • Our full C account of Russia is closer to atmospheric inversion than existing C inventory + model techniques • Combined top down–bottom up based approach has smaller uncertainties than pure top down approach • The combination of bottom up (FCA) with top down (atmospheric inversion) is the way to achieve ultimate verification • No “Missing Sink” IIASA Forestry Program 10
