Description

The repository contains site-by-site decadal trends computed with broadband aerosol optical depth (BAOD) derived from sunshine duration measurements at around thousand sites across the world since the late 19th century The data support the findings and results of the manuscript "Long-term trends in reconstructed atmospheric aerosol load based on large-scale sunshine duration records since 1900" by Wandji Nyamsi et al., submitted to the Atmospheric Chemistry and Physics journal.
