Finally, the original and constrained PFT maps were used to drive biomass 27 and albedo simulations with the ORCHIDEE model. 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. 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.

WebOct 25, 2024 · ORCHIDEE is the land surface component of the IPSL Earth system model ( Krinner et al. , 2005). When coupled with LMDZ, it has the same horizontal resolution and a global 4 m soil water depth represented with a two-layer bucket model, which is adequate to simulate evapotranspiration fluxes consistent with the data ( Guimberteau et al. , 2014).
