    Satellite simulators are used to calculate the brightness temperature (Tb) that would be measured by a space borne sensor under a\nset of atmospheric conditions accounting for the radiometric characteristics of the sensor and the orbital parameters of the satellite.\nIn this study, a simple approach is proposed for the parameterization of emissivity over land, a key parameter for the calculation\nof microwave Tb.The rationale is to simulate a large ensemble of emissivity values for each frequency and surface characteristics\nand then relate the most likely observed value with soil characteristics. The derived emissivity values are used for the simulation\nof Tb and simulated radiance is then compared with satellite observations. It is shown that this method improves the simulation\nof radiance and that it is suitable to provide a first guess of the emissivity value (a prior) that can then be refined using iterative\nprocedures.
