Short summary
A novel black carbon aerosol (BC) surface concentration retrieval algorithm was developed using MODIS data. The algorithm determined seasonal background aerosol model based on AERONET product, calculated the complex refractive index of the internal mixed aerosol, and combined 6SV2.1 to establish lookup tables to achieve the optimal estimation of BC fraction and column concentration. Using conversion coefficient generated by MERRA-2, column concentration was converted to surface concentration.
