Introducing CALIPSO’s Version 4 Level 2 Lidar Data Products

The NASA-CNES CALIPSO mission released Version 4.1 (V4.1) of their lidar level 2 (LL2) data products in November 2016. This new release from uses significantly improved retrieval algorithms to provide increased accuracy and substantially reduced uncertainties in the derived parameters. Here we present a comprehensive overview of the V4.1 LL2 data products, and show examples illustrating the improvements made in retrieving the spatial distributions and optical properties of clouds and aerosols.
