Space Research and Observations

Space based sensors can provide us with literally several times more data than ground based sensors. Most ground based and airborne sensors are only capable of detecting cloud to ground lightning, which is known to make up only about 25% of total lighting activity. This is further limited by the facts that ground sensors can only detect activity over land, and airborne sensors have a limited observation time. Thus, with these sensors alone, we are incapable of studying lightning activity over the two-thirds of the earth that is covered by ocean.

A space based sensor can detect lightning activity over land and sea, 24 hours a day, and can detect all forms of lightning. Thus, such sensors will allow the development of the first global database of lightning activity. Such information can be used for severe storm detection and analysis, and lightning-atmosphere interaction studies.
