TRIFFID - PLM_5, version 1

"TRIFFID (Top-down Representation of Interactive Foliage and Flora Including Dynamics)" is a dynamic global vegetation model, which updates the plant distribution and soil carbon based on climate-sensitive CO2 fluxes at the land-atmosphere interface. The surface CO2 fluxes associated with photosynthesis and plant respiration are calculated in the MOSES 2 tiled land-surface scheme (Essery et al (In preparation)), on each atmospheric model timestep (normally 30 minutes), for each of 5 plant functional types. The area covered by a plant type is updated (normally every 10 days) based on the net carbon available to it and on the competition with other plant types, which is modelled using a Lotka-Volterra approach. Soil carbon is increased by litterfall, which can arise from local processes such as leaf-drop as well as large-scale disturbances which reduce the vegetated area. Soil carbon is returned to the atmosphere by microbial respiration which occurs at a rate dependent on soil moisture and temperature." Source: TRIFFID documentation

Additional Attributes
Original Model: The original TRIFFID was implement in Fortran.
Purpose: To model the terrestrial carbon cycle component of the Hadley Centre's coupled climate-carbon cycle model.
