VLF Magnetic Spectrum Analyzer Data


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1977-11-03 to 1983-06-28


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, magnetic spectrum analyzer data are on binary magnetic tape created on a Univac 418 computer. Each logical record consists of 18 Univac 18-bit words. The data are year of data, day of year, seconds of day, logical record number, and one word each for the 14 channels of magnetic spectrum analyzer data (14 narrow-band channels from 5.6 Hz to 10.0 kHz). This data set was submitted for input to Coordinated Data Analysis Workshops and consequently only contains discrete periods during the time interval covered.
