CloudnetPy is Python software designed for producing vertical profiles of cloud properties from ground-based remote sensing measurements. The Cloudnet processing combines data from cloud radar, optical lidar, microwave radiometer, and numerical weather prediction models. Measurements and model data are brought into a common grid and classified as ice, liquid, aerosol, insects, and so on. Subsequently, geophysical products such as ice water content can be retrieved in further processing steps. See Illingworth et al. (2007) for more details about the concept.

CloudnetPy is a rewritten version of the original Cloudnet Matlab code. It features several revised methods, extensive documentation, and more.
