LANL PLASMA DATA FROM IMP-7 (2-min. resolution)

This home page provides access to the IMP-7 2-minute resolution data set 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 original ASCII data set is placed at SPDF's anonymous FTP site spdf.gsfc.nasa.gov in directory
spacecraft_data/imp/imp7/plasma_lanl/solarwind_2min/
At this directory a user can find a description of the data .

Time span 1972-10-06 - 1978-09-30
