“…First, we combined a random forest machine learning and a generalized additive mixed model to estimate daily high resolution (1 km × 1 km) visibility over the region using satellite-based aerosol optical depth (AOD) and airport visibility data. The spatially and temporarily resolved visibility data were then used to estimate PM(2.5) concentrations from 2001 to 2018 by converting visibility to PM(2.5) using empirical relationships derived from available regional PM(2.5) monitoring stations. …”
