Ceilometers are devices for measuring and recording the height of clouds using laser based LiDAR technologies. They also can measure the height of planetary boundary layer (PBL), which is the lowest layer in the atmosphere directly influenced by the Earth’s surface. This dataset consists of retrievals from an automated planetary boundary layer (PBL) algorithm. This algorithm is proposed as a common cross-platform method for use with commercially available ceilometers. For additional assistance in access and interpreting the data please contact the listed authors. This dataset is associated with the following publication: Szykman, J., D. Williams, V. Caicedo, R. Delgado, T. Knepp , K. Cavender, and B. Lefer.
