Abstract:
- Simulation of global plant microclimate off-line from climate maps.
- Full description of energy balance of vegetation and soil.
- Soil water (bucket), snow and skin reservoir budget.
- Phenology description under temperature, water and carbon limitation.
- Embedded photosynthesis scheme (Farquhar or Monteith) with 2-flux light absorption.
- Full description of stomata/water budget coupling, allowing simulation of fractionation processes of 13CO2 and CO18O.
- Description of vegetation-atmosphere CO2 exchange with plant and soil respiration.
- Exchangeable land-use maps: Wilson/Henderson-Sellers (atlas), Townshend/DeFries (Remote Sensing) or potential vegetation.
