the temperature rises reaching a constant value of about 95 K above 300 km. The upper atmosphere continuously leaks into outer space due to the weak gravity of Triton. The loss rate is about 1 nitrogen molecules per second, equivalent to about 0.3 kg/s.

Weather and climate

Nitrogen ice particles form clouds in the troposphere a few kilometers above the surface of Triton. Above them a haze is present extending up to 30 km from the surface. It
