WebORCHIDEE is used at the spatial grid of the meteorologi- cal forcings. This requires that the PFT distribution map, as well as the soil map that gives the proportions of silt, sand and clay (Zobler, 1986), are interpolated on the same grid. WebORCHIDEE trunk has three options to calculate the background albedo for the bare soil (PFT1): It can read the soil color (set alb_bg_model = y and alb_bg_modis = n) and account for soil moisture It can read the soil color (set alb_bg_model = n and alb_bg_modis = n) and ignore soil moisture

WebFinally, these new PFT maps have been used in two land surface models – Organising Carbon and Hydrology in Dynamic Ecosystems (ORCHIDEE) and the Joint UK Land Environment Simulator (JULES) – to demonstrate their benefit over the conventional maps based on a generic cross-walking table. WebMay 12, 2024 · Phenology is fully prognostic with PFT-specific phenological models as described in Botta et al. (2000) and MacBean et al. (2015). ORCHIDEE can be run from the site scale to the global scale, coupled with an atmospheric general circulation model, or in off-line mode forced by meteorological fields.

WebDec 20, 2024 · The PFT classification of FLUXNET is different from the one used in ORCHIDEE. To let ORCHIDEE simulate LE and the conductances without bias, we used a combination of ORCHIDEE PFTs to represent the vegetation type at each site (Table S1). Three simulations are performed at each site (Fig. 1).

WebFinally, the original and constrained PFT maps were used to drive biomass and albedo simulations with the Organising Carbon and Hydrology In Dynamic Ecosystems (ORCHIDEE) model.
