Detecting hot pixel induced steps in the Aeolus atmospheric signals

Kurzfassung

To improve Numerical Weather Prediction (NWP), the European Space Agency (ESA) satellite Aeolus, which is capable of providing global wind profile observations, was launched in 2018. Aeolus is equipped with a single instrument, the first ever Doppler wind lidar (DWL) operated from space, called Atmospheric Laser Doppler Instrument (ALADIN). The instrument emits laser pulses into the atmosphere and analyzes the frequency shift of the backscattered light, making use of the Doppler effect to determine the wind speed from the motion of aerosols and air molecules.
