In this paper, we compare lightning irradiance / lightning integral irradiance observed from GLIMS (Global Lightning and sprIte MeasurementS on JEM-EF) mission onboard ISS with current moment / lightning charge moment derived by ground based observation of ELF magnetic field observation, and verified the accuracy of the derived values. As a result, we got the high correlation (correlation coefficient > 0.76) between two values. We think that lightning charge moment, which is the energy of lightning discharge, estimated by only optical observation from space.
