Hi,
I will be measuring Aerosol Optical Depth using a sun photometer which I built myself. I will need to carry out Langley Calibration method and than use the attached formula to determine the AOD.
I will have all the variable except the ozone absorption constant (tau naught) and the rayleigh scattering constant (tau_R).
Where can I obtain these constants according to my location or maybe how can I determine them?
thanks
Brandon
