P78-2 SCATHA Preliminary Data Atlas.
Abstract
A preliminary study of the 100 eV to approx. 1 MeV plasma environment encountered by the P78-2 Spacecraft Charging at High Altitudes (SCATHA) satellite during its initial operation period was conducted. Forty-four days of 10-min averages of the four moments of the electron and ion distribution functions calculated from the SC5 and SC9 energetic particle measurements were analyzed to determine occurrence frequency, local time variation, geomagnetic activity variation, and L-shell variation. The single and double Maxwellian parameters derived from the four moments were similarly analyzed. The interrelationships between the moments and derived parameters were computed and the results compared with the ATS-5 and ATS-6 atlas of Garrett et al (1980). Results of this analysis establish a baseline range for the SCATHA plasma environment.
