The use of balloons by C. Moore to carry instruments into thunderclouds led to the erection of a balloon hangar on the open meadow 1 km northwest of the Laboratory in 1968.
The increased balloon and rocket probing of thunderclouds prompted the establishment in 1970 of a small restricted airspace, R5113, by the Federal Aviation Administration and the Office of Naval Research.
While much of the work at the Laboratory is directed toward the study of thunderclouds, lightning, and atmospheric electricity by Institute scientists, other investigators have undertaken a wide variety of research including investigations of cosmic rays, of ozone, and of the oxides of nitrogen.
