Validation data for the carbones ccdas system

Validation data for the CARBONES CCDAS system

  • 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)

    • Carbon in total biomass (kg)

    • Changes in pools per 5 years


Forest biomass dataset

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

  • 1 degree grid

  • Global cover

  • Mollweideprojection, Datum WGS84

  • NetCDF file
