Short summary
We present the first comparison of columnar aerosol properties recorded by sun photometry of Saharan dust between western Africa and Caribbean Basin. A comprehensive climatology of 20 years of data is presented in the two areas. To our knowledge, we present the first global climatology of columnar aerosols in the Caribbean Basin. Changes after transport in aerosol load, size distribution, shape, and absorbing and scattering variables are quantified using long-term records between 1996 and 2014.
