On the derivation of temperature from dayglow emissions on Mars' upper atmosphere

Abstract

We have used a General Circulation Model able to simulate dayglow emissions on Mars to quantify the accuracy of the temperatures derived from the scale height of the CO + 2 UV doublet and the Cameron bands on Mars. While the temperature derived from the UV doublet is accurate between about 160 and 200 km and at low solar zenith angles, the temperature derived from the Cameron bands is usually more than 20 K far from the actual temperature. The difference in the temperature derived from both emission system can provide information on CO abundance.
