Paper Abstract

The atmospheric turbulence effects on the light field at the altitude of the VIIRS from a ground based Lambertian source were investigated. It has been shown theoretically that the radiant intensity follows the Lambert’s law despite of turbulent perturbations. The corresponding average irradiance at the altitude of the VIIRS can be determined via the inverse square law. Light field scintillation was evaluated numerically by the discretized mode representation of the source and the multiple random phase screen simulation method. Our results will contribute to the study of using ground based light source for the validation/calibration of the VIIRS DNB.
