LANL PLASMA DATA FROM IMP-8 (hourly resolution)

This home page provides access to the IMP-8 hourly resolution data set which was created at SPDF by averaging 2-min resolution solar wind data from the Electrostatic Analyzer instument provided over the years by Los Alamos National Laboratory (LANL). Magnetosheath data were excluded from the 2-min data by LANL.
The ASCII data set is placed at SPDF's anonymous FTP site spdf.gsfc.nasa.gov in directory
https://spdf.gsfc.nasa.gov/pub/data/imp/imp8/plasma_lanl/solarwind_1hr/
At this directory a user can find a description of the data .
