Example of observed transmittances (Dec. 03, 2007, order 147, orbit 591, latitude \( 9^\circ {\text{S}} \), longitude \( 209^\circ \)) above an altitude of 95 km. These wavelengths are selected to visualize the observed spectra. The observed transmittances above 122 km are almost unity, because the solar light is not yet being absorbed by the atmosphere. At altitudes lower than 122 km, the standard deviation on the observed transmittance is small enough to isolate an individual observed transmittance
