1-Hour averaged Proton and Alpha Solar Wind Moments Data

Description

This hourly resolution data set was created at NSSDC in the year 2000 by averaging two-minute resolution solar wind data provided over the years by LANL. Magnetosheath data were excluded from the two-minute data by LANL. This collection supersedes hourly solar wind data provided by LANL over the years. These latter data were in various formats and contained many fewer parameters than the new data set.

These data are accessible on-line at: http://nssdcftp.gsfc.nasa.gov/spacecraft_data/imp/imp8/plasma_lanl/ in the directory solarwind_1hr.

This collection is also accessible with graphical display and listing capability and with time and parameter subsetting capability at: http://nssdc.gsfc.nasa.gov/ftphelper/imp_lanl.html
