Abstract :
This article presents a preliminary semi-automated range-interval segmentation toolset for the identification of: 1) the apparent range of full overlap, 2) the clear-sky level (i.e., the molecular level), and cloud layers (cloud-base, cloud-peak, and cloud-top range), and 3) apparent homogeneous extinction intervals.
