Presentation Transcript

  1. Biomass benchmarking • 400-800 PgC range in TRENDY models • Plot-scale and satellite benchmarking

  2. Biomass benchmarking • Human disturbance (44 Mkm2) and natural disturbance (i.e., fire: 2-3 Mkm2 a-1)

  3. Biomass benchmarking Global Forest Age

  4. Biomass benchmarking 1850 1870 …. 1990 2000 Global biomass-age curve

  5. Biomass benchmarking Potential biomass reduction with age (KgCm-2) 448 PgC-age corrected 752 PgC-potential Pan et al. 363±28 PgC

  6. Biomass benchmarking Standard ORCHIDEE biomass (tC ha-1) Age-corrected ORCHIDEE biomass (tC ha-1)

  7. Biomass benchmarking Underestimate (land cover?) Overestimate (Vcmax, turnover) Agreement (±25 KgC m-2)
