The main objectives of the mission was to supply unique data set of vertical cloud and aerosol profiles.\r\n\r\nThis dataset contains cloud and aerosol lidar level 2 Aerosol Profile Version 3-01 data derived from Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) Level 1B product with uniform horizontal resolution of 5 km and ancillary data. There are no layer descriptors included in the datasets, and the spatial distribution of the aerosol layers depends on the aerosol layer fraction and atmospheric volume description parameters. The aerosol backscatter and extinction coefficients are obtained through the CALIPSO Lidar Ratio selection algorithm. In Version 3-01, L2 products use enhanced daytime calibration, improved cloud-aerosol discrimination algorithm with removal of a bug in the cloud clearing code, and the newly introduced cloud thermodynamic phase assessment algorithm.","keywords":"NASA, CALIPSO, CALIOP, Cloud,
