Gridded satellite products provide (computationally less-intense) opportunities to compare and contrast parameters from different versions/sensors. In the present study, Level-3 (L3) Cloud Aerosol Lidar with Orthogonal Polarization (CALIOP) aerosol products from the most recent release (version 4, V4) are compared with its earlier version (version 3, V3) products.
•CALIOP global mean V4 total-AOD is higher than the V3 AOD.
•CALIOP V4 AODs are comparatively closer to MODIS AODs than V3 AODs are.
•Differences in V4 and V3 altitudinal aerosol distribution vary spatio-temporally.
