Spatial correlation estimates based on satellite observations corrected with the prior knowledge on sensor devices' technical characteristics

Giuseppe Arbia & G. Lafratta
In many empirical studies spatial correlations are used to identify the distance above which dependency is negligible, to assist the choice in locating a systematic grid of sample points in ground surveys. However, estimates are undermined by the fact that our inference is based on satellite data that are only an approximation of the ground truth, due to the presence of a series of disturbing factors like (e.g.) light scattering, presence of obstacles (like clouds),...
