Abstract

This paper performs a study on the application of the triangulation method to infer the height of the atmospheric airglow emission layer. This method determines the maximum correlation for regions of interest between two consecutives images of the same structure in the airglow, obtained by an all-sky imager. The method sets the linearization height of the first image taking with reference the nominal altitude of the studied airglow layer and varies the reference height of the second image to another various altitudes. Then, it is applied the cross correlation in a given area of the image where there is a gravity wave structure. The height/correlation profiles show a convergence of the maximum correlation around the nominal altitude fixed at the first image.
