Average of all normalized extinction coefficients for morning high-latitude (latitude \( > 60^\circ \), black line), evening high-latitude (latitude \( > 60^\circ \), red line), morning low-latitude (latitude \( < 60^\circ \), blue line), and evening low-latitude (latitude \( < 60^\circ \), green line) observations. The average of the variability is 34.3% for the morning high-latitude observations
