Résumé : The JEM-EUSO fluorescence telescope will observe UV emission from Ultra High Energy Cosmic Ray (UHECR) induced Extensive Air Showers (EAS) from space. Observation with a space-based telescope has an advantage compared to the ground-based observations, because the EAS signal from the upper atmosphere above 10 km altitude (above the top of the Troposphere) is never obscured by optically thick clouds for such a telescope. Nevertheless, proper interpretation of the UV signal from the lower parts of some 60-70% EAS detected by JEM-EUSO, including the reconstruction of the energy, direction and identity of the UHECR particle, requires a detailed knowledge of the influence of clouds and aerosols on the detected UV signal. The Atmospheric Monitoring system of JEM-EUSO will use the LIDAR, operating in the UV band, an infrared camera, the UV images of the night sky obtained by the JEM-EUSO telescope itself, as well as real time global meteorological data and models to deduce the distribution and properties of clouds and aerosol layers in the atmospheric volumes around the location of each triggered EAS event. In this contribution we describe the set-up of JEM-EUSO Atmospheric Monitoring System and characterise its performance. In addition, we show that the reconstruction of UHECR events will be possible also for events occurring in cloudy sky conditions if the data of the Atmospheric Monitoring are taken into account.
