The Micropulse Lidar Cloud Mask Machine Learning (MPLCMASKML) value-added product is an alternative approach to traditional cloud detection algorithms. Taking advantage of machine learning capabilities and capitalizing on the trained eye as an interpreter of lidar images, a deep neural network is trained to recognize desired cloud features in MPL lidar data.

This approach has been applied to data from the ARM fast-switching polarized micropulse lidars to develop a machine learning model that can segment images semantically and produce pixel-to-pixel predictions of clouds in lidar images (Cromwell and Flynn 2019). In addition to these cloud predictions, the model provides a confidence rating of each pixel prediction. MPLCMASKML provides the cloud mask as well as the number of cloud layers and the cloud layer boundaries.
