Temperatures in the Martian atmosphere

This image shows the thermal field in the Martian atmosphere measured in Mars Express orbit 71 (top panel), and in orbit 4520 (bottom panel).

It can be seen that the temperature at 45 km altitude was 170 K (-103°C) during orbit 71 and 210 K (-63°C) in orbit 4520. But at 10 km, the temperature increased from 210 K to 250 K (-23°C).
