WebSep 14, 2015 · To achieve assimilation of surface albedo during the snow season into the land surface model ORCHIDEE, we need the blue-sky albedo ( αblue) that refers to the instantaneous surface albedo measured under natural daylight illumination. αblue can be approximately expressed as a linear combination of black ( αblack) and white-sky albedo ( … WebORCHIDEE has been recently endowed with a new 11 layers hydrological model which allows to refine the representation of soil water transfers. This discretization scheme offers a unique opportunity to match as closely as possible the representative depth of the satellite instrument products.

WebApr 1, 2024 · The ORCHIDEE LSM is the land component of the French Earth System Model (ESM) developed at the IPSL (Institut Pierre Simon Laplace). It simulates the interactions between the biosphere and the atmosphere by modeling the water, energy, and carbon cycles ( Krinner et al. 2005 ).
WebSep 14, 2024 · Land surface models (LSMs) are key tools to quantify these surface fluxes and to better the representation of their interactions. They allow the coupled simulation of the fluxes of water, energy and carbon between the surface and the atmosphere and are a crucial component of numerical weather models and earth system models.
