This module allows you to plot altitude profiles of the radiation flux from the Sun as it is absorbed coming into the atmosphere, the number of electron-ion pairs produced, and the resulting density in an α-Chapman layer where the recombination rate is proportional to the square of the electron number density.
We assume the Chapman production function peaks at 120 km and that at 0° solar zenith angle and with an atmospheric scale height of 10 km the production function is 8 × 103 electrons cm-3 s-1.
