WebORCHIDEE, surface roughness and surface albedo were identified as the key variables which need to be computed from the simulated state of the vegetation. In both cases the grid … 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). This spatial resolution is clearly not sufficient for future local-
WebMar 29, 2024 · Orchidee_pft.def files are independent from the model configuration and whether the land-only or land-atmosphere set-up is used. Implication for the ORCHIDEE source code. The outcome of the optimization is often a modifier. This is a very elegant approach which separates the original parameter value from its optimized value. 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).
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.

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. This study demonstrates that remotely sensed biomass data can be used to better constrain the share of dense forest PFTs but that additional information on bare soil ...
