  • Forest pools and uncertainties (annual)
    • Forest area (km2)
    • Timber volume (m3)
    • Aboveground biomass (kg)
    • Carbon in aboveground biomass (kg)
    • Belowground biomass (kg)
    • Carbon in belowground biomass (kg)
    • Total biomass (kg)

Data
  • FAO-FRA (Global Forest Resources Assessments)
  • MCPFE (Europe)
  • UNECE
    • Per Country
    • 1948-2011 (minimal 5 year interval)
    • Forest Area
    • Growing Stock
  • IPCC 2006 good practice guidance for biomass conversion and expansion factors to estimate above-ground and below-ground biomass and carbon
processing
Processing
  • Quality check: remove outliers
  • Interpolate in between data points
  • Extend values outside data range (flat)
  • Gridding, relative to current forest cover map
  • Assign uncertainties

uncertainty assessment
Uncertainty assessment
  • Base uncertainty
    • 3 classes (1,2,3 points)
      • Trend over all records
      • Coefficient of variation of detrended records
  • Methodology uncertainty
    • 0.025 point per year (pre 1990)
  • Interpolation uncertainty
    • 0.1 point per year
technical specifications
Technical specifications
