Fractal geometry features of aerosol particle and its contribution to atmospheric optical property: development of Fractal Aerosol Cluster Model and its validation of atmospheric visibility during a heavy haze event

-------------------------Content of the dataset-------------------------******  the experiment case (EXP) ;  the control case (CTR)  ******

1. Meteorological elements.tar contains observational and simulated data for T2, WS, RH, and PM2.5 time series, which can be used to plot Figure 4 and build Table 2

2. Planar distribution.tar contains the horizontal spatial distribution data of aerosol extinction coefficients simulated by CTR and EXP for the four typical moments selected in this paper, which can be used to plot Figures 5, 6, and 7

3. PM.rar contains the vertical profile data of simulated Particulate Matter concentrations by CTR and EXP during the study period in the paper, which can be utilized for drawing Fig. 11.

4. Timeseries.tar contains observational and simulated data for time series of atmospheric visibility and surface shortwave radiation, which can be used to plot Figures 5, 6, 7, 8, S1, and build Table 3

5. wrfbiochemi.rar contains the biogenic emissions data for simulation both for CTR and EXP.

6. wrffirechemi.rar contains the biomass burning emissions data for simulation both for CTR and EXP.

7. wrfchemi.rar contains the Anthropogenic emissions data for simulation both for CTR and EXP.

8. The file module_optical_averaging.F contains the main code of the improved visibility model, the Fractal Aerosol Cluster Model

(FACM), which is coupled to WRF-Chem and used by EXP. It is located in the chem/ directory and called by optical_driver.F.
