Alouette Synoptic (Alosyn) Scaled Data on Microfilm

NSSDCA ID: SPIO-00308

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1962-09-29 to 1964-08-31

Description

This data set, prepared at the Communications Research Centre in Ottawa, Canada, consists of Alouette 1 synoptic data (Alosyn) on reels of 35-mm microfilm. The Alosyn data are tabulations of selected ionospheric parameters which were read (scaled) from the ionogram and, in some cases, also calculated from other scaled values. Four parameters are presented chronologically: (1) plasma frequency at the satellite, (2) plasma frequency at the F2 maximum, (3) maximum frequency of observed sporadic E, and (4) strength of ground echoes. Supporting information includes for the spacecraft position: Greenwich and local mean time, location, magnetic dip, solar zenith angle, Kp, and quality and accuracy notations for some of the scalings. These data are also available on magnetic tape as data set 62-049A-01C and on microfiche as data set 62-049A-01K.
