It is common knowledge that the scattering of blue photons by the atmosphere is more significant than for other colors hence aerial images of earth look bluesh. The graph below obtained from MODTRAN 'allegedly' supports this fact. While trying to quantify this effect, I've preformed several calculations According to my calculations, since the camera counts photons and since one has to divide energy by hc/lambda to obtain #photons we obtain a monotonically decreasing scattering function multiplied by the monotonically increasing lambda function, which yields a relatively constant product (high energy at low wavelengths represent same photon number as low energy at high wavelengths). This product, multiplied by each of the 3 color bands (R, G and B) gives a similar result for all channels. In other words, the sun scattering is relatively equal for all three RGB channels of a standard CCD camera. My question is why are the images bluesh? Am I missing something?? Thanks!
