GLM
GEO Lightning Mapper | Operational
| Detect total lightning flash rate over near full disk. | Lightning imager | |
LIS
Lightning Imaging Sensor | Operational
| Global distribution and variability of total lightning. Data can be related to rainfall to study hydrological cycle. | Lightning imager | |
LMI
Lightning Mapping Imager | Operational
| Lightning mapping for locating thunder storms in flooding season, CCD camera operating 0.77 µm to count flashes and intensity. | Lightning imager | |
LI
Lightning Imager | Being developed
| Real time lightning detection (cloud-to-cloud and cloud-to-ground strokes, with no discrimination between the two), lightning location. | Lightning imager | |
