ISIS-1,CEP,Electron Density and Temperature, ASCII, online

Description

This data set, prepared by the principal investigator contains 17 months of electron number densities and electron temperatures observed at the satellite. The data set was originally provided on an EBCDIC magnetic tape written on an IBM 360 computer and is now available in ASCII format at:

Subsetting and plotting capabilities are provided through the ATMOWeb interface at

The data have been calculated from the telemetered retarding potential curves. Included in the listings for each data point are telemetry station, orbit number, date, Greenwich and local mean time, geodetic coordinates, geomagnetic latitude and longitude, geomagnetic-field intensity and dip angle, solar zenith angle, solar 10.7-cm flux, planetary Ap index, and satellite potential. Temperature data occur about every other data point, alternating with electron density values. Gaps in time coverage are usually a few orbits or less. The data have gaps in coverage caused primarily by limitations (or failure) of the tape recorder, and limitations of experiment scheduling. These same data are available on microfilm as data set 69-009A-07B. Summary plots at 1-week intervals are shown in data set 69-009A-07D.
