Chatanika moves to polar cusp



Scientists in the fields of aeronomy, spate physics, and meteorology have used the Chatanika incoherent-scatter radar extensively over the last 11 years. During this past solar cycle, 11,718 hours of data were collected, resulting in substantial increases in knowledge of the high-latitude ionosphere and auroral processes. The 141 journal articles and 13 Ph.D. theses published since 1972 attest to the facility's productivity.

On March 1, 1982, operations in Alaska ended so that the radar could be relocated to a higher invariant latitude (see Figure 1). The new location will be Sondre Stromfjord in Greenland, invariant latitude 75°. At this location, it will be the northernmost station of a longitudinal chain of incoherent-scatter radar facilities (Sondrestrom, Millstone Hill, Arecibo, and Jicamarca) stretching from the polar cap to the magnetic equator, and the incoherent-scatter technique, applied successfully in the auroral zone, will be available for polar cap/cusp research for the first time.
