Estimation of N2+ produced by EUV

nFrom data obtained at day time, we can know relation between solar zenith angle and intensity at  the zenith. nTo differentiate the data, intensities of N2+ emission at each altitude are estimated.

To estimate intensity profile of N2+ emission.

Intensity of N2+ emission decreases 4 order with the increase of altitudes from 100km to 200km.
