Abstract:The mapping of the lightning optical pulse detected by the Lightning Imaging Sensor (LIS) is compared with the radiation sources by Lightning Detection and Ranging (LDAR) at KSC and the National Lightning Detection Network (NLDN). Flash-based comparisons are done for the 15 August 1998 case including 122 flashes. The temporal and spatial differences are examined. For ground flash, the time difference of the first LDAR source and first LIS event has a mean of 0.23 s and the total duration of the flash has a mean of 0.28 s, compared to 0.56 s by LDAR. The LIS records the subsequent return stroke or K-change component. For cloud flash, the time difference has a mean of 0.2 s and the total duration of the flash has a mean of 0.38 s, compared to 0.44 s by LDAR. The LIS also records cloud flashes at higher altitude. The location differences are about 4 km for cloud flash and 12 km for ground flash.
