RAMI2 phase
Within RAMI an environment is deemed heterogeneous if its properties must be considered dependent of geographical location (horizontal spatial coordinates). For the 'heterogeneous environments' category of RAMI-2 all radiation transfer simulations are to be performed with scatterers having optical properties corresponding to typical values encountered in the solar domain, or more specifically, the red and near infra-red spectral bands.
The following Figure provides information as to the local model deviation of the various participating models for 1) the real zoom-in (Mixed vegetation), 2) the topography (Coniferous Forest), and 3) the Floating spheres experiments. Green (red) values indicate models that are in good (poor) agreement with all other models, grey values indicate missing or incomplete data. Ideally there should be no grey colour in the graphs below. Models that do not participate in all of the prescribed test cases can only be evaluated in a partial manner at best.
The next few figures provide the same kind of information as the above graph but for the various radiative components that make up the overall BRF, namely:
The various testcases that are defined within this phase of the RAMI initiative can be visualized on their respective description pages:
