Fig. 13

Example of the averaging kernel matrix (colored lines) and the column averaging kernel (black line). They are calculated under the diffusive reflectivity of 0.3 and the solar zenith angle of 30°. It corresponds to cases 1, 2, and 3 from the top, and CO₂, CH₄, H₂O, and CO from the left. The vertical axis corresponds to the layer number of the atmospheric layer. It is counted from the top-of-the-atmosphere toward the surface. Colors of the averaging kernel matrix also correspond to the layer number of the atmospheric layer, in the order of purple (top-of-the-atmosphere), blue, green, orange, and red (surface)
