Research field 3: Investigations of the middle Earth atmosphere with lasers. Project 3.1: Temperatures at heights between 80 and 100 km
Abstract
A lidar experiment was performed to determine temperature profiles in the mesopause. The measuring apparatus contains a powerful (2 MW pulses), very narrow band (about 0.13 pm) and tunable laser. Free Na-atoms between 80 and 110 km are excited to resonance fluorescence which is observed on Earth with a telescope to deduce the atmospheric temperature. The Winter campaign shows temperatures lower than expected.
