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).

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). WebThe current ORCHIDEE PFT map is based both on the International Geosphere-Biosphere Programme (IGBP) 1km global land cover map (Belward et al., 1999) reduced by a dominant-type method to 5km spatial resolution, and on the Olson classiﬁcation (96 types) (Olson et al., 1983).
