High Altitude Research

According to a recent communication from R. H. Simpson of the U.S. Department of Commerce Weather Bureau in Washington, D.C., another high altitude laboratory should be added to the list of such stations given in the May 1952 issue of Physics Today (p. 28). A new geophysical observatory, he points out, has been established at the summit of Mauna Loa (altitude 13,453 ft) on the island of Hawaii. Equipped at present as a weather observatory, it is attended by U.S. Weather Bureau personnel stationed at Hilo, Hawaii.
