One will cover the 200-2000 km range and measure electron number densities, temperatures and composition with a time resolution of 25 min. at low altitudes and 1 and one-fourth hrs. at high altitudes. The other program will measure number densities, temperatures, and photo-electron fluxes in the 250-500 km region (i.e., pure 0+ region) with a time resolution of approximately 5 min. By increasing the efficiency of the CDC-3300 computer system, these programs increase the capabilities of the Observatory and improve the value of the data for geophysical studies. 46 pp reformatted digital eng Copyright is held by the author, unless otherwise indicated.
