Cover Story: MIPA (Morphological Image Processing Approach) is a novel algorithm developed at CNR-IMAA within the framework of ACTRIS for retrieving Atmospheric Boundary Layer Height (ABLH) from Lidar observations. The algorithm has been tested on multiple datasets, generally showing good agreement with established ABLH retrieval techniques. Unlike traditional methods that analyze Lidar data profile by profile, MIPA adopts a fully image-based strategy: it processes entire Lidar time series as two-dimensional images, therefore accounting for temporal correlations in ABLH determination. By combining morphological filtering and object-oriented analysis, MIPA achieves robustness across different sensors and wavelengths. This opens the way to improved characterization of ABLH at continental and even global scales through multi-sensor approaches. View this paper
