Short summary
The long-term (2002–2016) variability of global and diffuse PAR over the central Mediterranean is investigated based on measurements from Lampedusa. PAR modulates biological processes and this study provides useful insight into its variability. Seasonal and interannual variability of global and diffuse PAR is characterized and the effects of clouds are quantified. The analysis suggests that 77 % of the global PAR interannual variability may be ascribed to clouds.
