From: Evaluation of a method to derive ionospheric conductivities using two auroral emissions (428 and 630 nm) measured with a photometer at Tromsø (69.6°N)

Fig. 17

Temporal variations of the ratios of height-integrated conductivities for October 10, 2002; temporal variations of ratios of height-integrated Hall (left) and Pedersen (right) conductivities as well as intensity ratios of 427.8 to 630 nm for October 10, 2002. Upper panels: Red and blue circles denote the ratios of values when the cross-sectional values are doubled or halved to the normal values, respectively. Lower panels: same to the upper panels but for atomic oxygen density
