Compute anthropogenic fraction from CAMS speciated AOD


I have attached a Python script here for the computation of F_anthropogenic over the Indian oceanic region (following flow diagram of section 3 in Bellouin et al., 2013 ACP) using CAMS speciated aerosol optical depth daily data ( that includes Black carbon, organic matter, sea-salt, and sulphate) and wind speed at 10 meters. 

I would be grateful if anyone could take a moment to review it and suggest correction if any...Thanks
