Turbid

RAMI3 phase

This set of experiments was suggested to simulate the radiative transfer regime under conservative scattering conditions for homogeneous environmental scenes with sparse, medium and dense foliage concentrations, that are represented by a 'gas' of dimension-less particles (to be treated as a turbid medium), located over a horizontal plane standing for the underlying soil surface.

The particles were randomly distributed non-dimensional scatterers characterized by the specified radiative properties (reflectance, transmittance), and the orientation of the normals to the scatterers followed either an erectophile or a planophile distribution function. The radiative properties of the underlying soil were also specified (in this case a simple Lambertian scattering law). The particular values selected for these input variables represented classical plant canopy conditions.

The tables below provide the details required to execute each of the experiments in this category. Every table is preceeded by the corresponding experiment identifier tag <EXP> that is needed in the naming of the various measurement results files (see file naming and formatting conventions).
