update on input data
Update on input data
  • Soil Data
    • Soil texture - Combination Quesada and IGBP-DIS (1km)
    • Soil depth - 4 meters for each grid cell- Run with 10m
  • Soil Properties
    • Pedotransfer Functions – Campbell
    • Pedotransfer Function – Tomasella & Hodnett - David
  • Land-use data
    • preliminary regional simulations – potential vegetation;
    • Historical land-use data are from Hurtt et al. land-use data.
  • Atmospheric CO2
    • Pre-industrial constant atmospheric CO2 concentration (278 ppm) are used for model spin-up;
    • Changing atmospheric CO2 concentration are used for model simulations from 1715 to 2005.
update on input data1
Update on input data
  • Meteorological drivers: Sheffield et al. corrected NCEP data at 1-degree resolution from 1970 to 2005.
  • Meteorological driver for future runs: Corrected GCM data
  • Meteorological data from Jingfeng
    • Time period: 1990-2010
    • Time resolution: hourly
    • Spatial resolution: met data 10km
update on validation data
Update on validation data
  • Carbon fluxes - Reichstein, 2010 Science - MODIS
    • GPP/NPP / NPPwood – Malhi et al.
    • NEE
  • Ecological stock and state variables
    • Aboveground biomass (AGB)
      • Saatchi et al.
      • Alessandro Bacini
      • Malhi et al, 2006
    • Canopy height –
      • Lidar-GLAS not very well comparable ??
      • check with Alessandro Bacini product - Andrea
    • LAI – MODIS
    • Litterfall – Malhi et al.
  • Soil Carbon – SOTER - David
  • Hydrological components
    • Total runoff/discharge/drainage - Mike
    • Water Storage Change- GRACE - Mike
    • Evapotranspiration (ET)
      • Jung et al, 2010 Nature, Josh Fisher, Malhi et al
  • Ke
    • - Remote sensing data

future runs
Future runs
  • First Preliminary Simulation
  • Second Simulation: Coarse Resolution
    • Potential Vegetation , soil depth 10m – 1970-2005
    • Land Use Change, soil depth (?) – 1970-2039
  • Third Simulation: High resolution
    • Quesada Soil texture data
    • Soil Depth to be defined
    • Jingfeng Met drivers
      • Starting in 25km
      • Time step: hourly
      • Time interval: 1990 - 2010
future analyses
Future Analyses
  • Comparisons Between Model and Observations
    • AGB, canopy height, carbon flux, soil carbon
  • Energy Balance
  • Carbon Flux
  • Water Cycle
  • Is the magnitude of the CO2 fertilization effect in the regional simulations reasonable?
  • Examine patterns of inter-annual variability including the 1983 and 1998 El Nino events, and the 2005 and 2010 droughts (check for Met drivers)
  • Evaluate model AGB predictions against Saatchi biomass map at an aggregated regional scale rather than the grid cell scale.
  • Is there higher biomass in the Eastern Amazon as predicted by ED and IBIS?
