In atmospheric correction, how seadas calculate the interaction term between molecular and aerosol scattering (Rho-ra)? is there any LUT?
Assuming you are familiar with the Gordon and Wang 1994 algorithm, there is a geometry-specific quadratic equation that relates single to multiple scattering for each aerosol type (aerosol model). The coefficients of those quadratics are stored in the aerosol LUTs.
Sorry, would you like to show me the geometry-specific quadratic equation here, please
I found what I need in your answer for other question.
The poly coefficients are applied to rss (in log space) to derive rms. This is from the routine rhoas_to_rhoa().
lnrhoas = log(rhoas[iw]*aeroob(sensorID,iw,cf,wv));
rhoa[iw] = exp(a + b*lnrhoas + c*lnrhoas*lnrhoas);
What the meaning of "aeroob" ?
aeroob is a function that performs an out-of-band water-vapor correction.
See the code aerosol.c
