Figure S1. Model-simulated (WRF-Chem) aerosol volume size distribution as compared to AERONET data. Data averaged over the period of August 1-22, 2015 at KAUST.
Figure S2. Spatial pattern of cloudwater mixing ratio at a cloud-level height (~570 hPa, ~ 4.6 km) in terms of total, indirect, and direct effects averaged for August 4-31 (2006-2015). Areas where the change is statistically significant at 5% significance level are marked by black dots.
