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 ppengCopyright is held by the author, unless otherwise indicated.
