Quasi-Static Electric Field Data


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1977-11-03 to 1980-05-11


This data set is proprietary and not for distribution. It is submitted by experimenters to NSSDC for the purpose of the Coordinated Data Analysis Workshops (CDAW). The data sets submitted for CDAW are usually small, and the time coverage is usually scanty within the time span indicated. However, this data set (or part of it) may be provided to the general science community through an online data set in CDF format. For more detailed description, as well as access information, please contact the NSSDC Request Coordination office at

These experimenter-supplied, electric field data are on binary magnetic tape created on a PDP-11 computer. Each physical record consists of one record header and 48 data groups. The 80-byte record header contains year, day of year, and hour of day; satellite distance from earth center; local time; latitude; transformation matrix from B-local dusk magnetospheric coordinates to geocentric solar magnetospheric coordinates; number of the j X B bias values, used as a correction, and time offset of the j X B bias for 8 pairs of values; and guard filters and shield mode flags. The 72-byte data group consists of time offset for group to be added to time given in header; electric field coordinates in B-local dusk magnetospheric and satellite-centered solar ecliptic systems; standard deviations of the electric and magnetic field components; number of available electric field and B-values; electric field phase, theta and phi in geocentric solar magnetospheric coordinates; filter output; altitude; and geocentric solar ecliptic coordinates. This data set was submitted as input for Coordinated Data Analysis Workshops and is therefore limited to discrete periods within the time interval covered.
