This set of experiments was suggested to evaluate the models under extreme conditions, in particular to verify their ability to conserve energy. The proposed scenes constitute a special case of an homogeneous environment in which the values selected for the input variables were not meant to represent any particular realistic conditions, but, rather, to permit a detailed evaluation of the performance of the participating models. Two types of homogeneous environments are being considered:

Homogeneous environments are typically represented with 1-dimensional models, where the only spatial coordinate represented explicitly is along the vertical. However, for the case of finite-sized scatterers, the geophysical medium is intrinsically 3-dimensional, since the individual scatterers are oriented finite size objects, even though it may be simulated statistically without an explicit representation of horizontal variations.
