AEOLUS underwent a long development led by Airbus Defence and Space both for the LIDAR instrument (ALADIN) in France, and the platform in the UK, and was successfully launched into a Sun-synchronous 320 km dawn-dusk orbit by a Vega launcher in August 2018. The ALADIN Doppler wind LIDAR is pioneering the application of such kind of instrument in space and widens the field for space based LIDAR applications. Initially the mission was designed to be a demonstrator but can be actually considered as operational as the data are used routinely with positive impact on the Numerical Weather Predictions (NWP) models after less than one year of operations in-orbit. After four years of operational lifetime, and also thanks to a strong support to in-flight operations, AIRBUS has learnt, together with ESA customer and scientist user teams, many things about ALADIN LIDAR instrument behavior and its performance monitoring in orbit. While temperature and power telemetries monitoring are quite standard in post-delivery, the follow up of the instrument optical alignment and performance is less direct and lesson learnt show it can be however very profitable in particular for the first UV LIDAR in orbit. The ALADIN architecture is recalled with its measurement principle, and its calibration mode and measurement mode, summarizing the available data for monitoring its behavior in orbit: this covers far field pattern from the atmospheric echo, or near field pattern from the atmospheric echo or internal calibration path; this allows to derive alignment stability of the transmitter and receiver part of the instrument. Also, spectral calibration curves trends allow to retrieve information’s about spectrometers stability. In addition, energy monitoring trend are presented with several means available, and linked lessons learnt are driven. As an important contributor for ALADIN performances, the telescope stability is analyzed and thermal correlation presented with representative Earth albedo maps. The telescope stability is shown as a contributor to link budget but also to spectrometers systematic error limitation due to their sensitivity to variations of divergence and line of sight (angle of incidence). As other key element, the CCD sensor "hot pixel" observation is described with the workaround solution operation at instrument allowing to remove their negative impact on measurement data. Overall conclusion is driven with lessons learnt and perspective for a follow on instrument.
