Observed dependency of the ratio between the turbulent vertical flux (Fb) and the solar radiation at the top of the atmosphere (Ktop) as a function on observed particulate mass (PM2.5) concentration.
The fitting includes all the data points. To guide the eye, the PM2.5 data is binned in five batches where the median is shown as a line whereas the outer boundaries of the boxes represent 25 and 75 quartiles and the dashed lines present interquartile range (IQR). Dashed vertical lines represent 5 and 95 percentile ranges in each bin. Only daytime conditions between 10:00 and 14:00 local time from non-rainy periods are considered. Atmospheric RH during the measurements is indicated with the color of the data point. The dependency of the other radiation components are presented on PM2.5 is presented in Supplementary Fig. A1 and on BC concentration in Supplementary Fig. A2.
