MERGE IMP, WIND, ACE and Geotail Magnetic Field Data
These hourly data were created as part of OMNI data preparation. The Wind and ACE averages were built at SPDF from higher resolution data time-shifted to Earth from the Wind and ACE locations. Details on the time shifting you may find HERE. 
Time span of data set:

 IMP8   1995-01-01 - 2000-06-09 
Geotail 1995-01-01 - 2006-12-31
 WIND   1995-01-01 - 2024-08-16
  ACE   1998-02-05 - 2022-04-22
