Abstract
Always, in the atmosphere of the earth we live in is a luminous phenomenona (Fluorescence by cosmic rays, lightning and aurora etc..) has been occurring. JEM-EUSO (Extreme Universe Space Observatory onboard Japanese Experiment Module) experiment is the observation that aims to capture the luminous phenomenon in earth's atmosphere from orbit. JEM-EUSO telescope observations have been using a Fresnel lens of the world's largest. The observation area (250km radius at the sea level) is extremely larger than the telescope installed on the ground to captures the luminous phenomenon. The main target of EUSO is to capture the fluorescence emission caused by UHECR (Ultra-High-Energy Cosmic Ray). This way that is extremely large observation area for UHECR will be frontier for astronomical observation of charged particles for relatively near space (50Mpc). Because JEM-EUSO observe fluorescence in the atmosphere of the earth from space, it is necessary to measure the state of the atmosphere (cloud cover and transparency in particular) for the calibration. The infrared camera mounted on the JEM-EUSO is used to measurement of cloud coverage and cloud top height. For the atmospheric transparency measurement and calibration of the cloud top height, we use the LIDAR system using EUSO's telescope and the laser. It is also possible that in addition to this, to know the state of the atmosphere based on the background light captured by EUSO's telescope. These measurements of atmospheric conditions for the observation of UHECRs is not only calibration data. The atmospheric observation that covers the entire ground is the vital information in the geophysical. Furthermore, it is possible to measure light emission by lightning or meteor that occur in the field of view during observation of darkness in the JEM-EUSO. Expected by combining a lot of measurement, to understand of the earth and proceed further.
