During its approximately 4 1/2 years of operation (until March 20, 1982) the Lockheed Plasma Composition Experiment on ISEE 1 [Shelley et al., IEEE Trans. Geosci. Electron., GE-16, 266, 1978] gathered a very large and in many respects entirely unique set of data on the magnetosphere, magnetosheath, and solar wind ion populations with energies in the 0-18 keV/e range. Due to the orbital characteristics of the ISEE 1 spacecraft, data were obtained in regions of space where no ion mass spectrometer had been flown before, and the few such instruments that have since been flown in the same general regions, especially the geomagnetic tail beyond 10 earth radii, have either been designed for much more energetic ions or have failed to provide useful data.
Data from the first 28 months of operation (the so called "prime" period of the ISEE Mission) have been archived in several different formats at the National Space Science Data Center, or NSSDC, at NASA Goddard Space Flight Center in Greenbelt, Maryland, USA. On line data from one particular format, the one most recently used (1991) is available on this server. The data set has the NSSDC index numbers 77-102A-12I and -12J and covers data from November, 1977, through February, 1980. Complete copies are kept on magnetic tape and on hard copy at Lockheed's Research and Development Division in Palo Alto, California (see below for contact). A subset of these data is usually also kept on a computer disk at Lockheed. This same format may be used to archive the remaining 25 months of data sometime in the 1995-1996 time frame.
