This directory consists of annual subdirectories containing
daily files of 20-sec particle count rate data from the JHU/APL
CPME and EPE experiments. Merged into each record are IMP 8
magnetic field and MIT plasma parameters. Each such annual
subdirectory also contains a subdirectory of daily attribute
files.
The content and format of each 20-s record, plus links to
further descriptive material, are given at
http://spdf.gsfc.nasa.gov/imp8/imp8_merged.html
Brief descriptions of this data set and its source spacecraft
and experiments are in the NSSDC information files at
