Abstract
Systems and methods are disclosed to detect cloud-to-ground (CG) strokes that include or are followed by continuing current. As an example, earth-based lightning data may be generated for one or more lightning pulses detected in an environmental space using multiple earth-based lightning detection sensors. Space-based lightning data may be received for one or more optical signals detected in the environmental space using one or more space-based lightning detection sensors. It may be determined whether one or more lightning pulses is a CG stroke based on the earth-based lightning data. In response to determining that a given one of the one or more lightning pulses is a CG stroke, it may be determined whether the CG stroke includes or is followed by continuing current based on the space-based lightning data.
