This page shows the data sources and their locations that we used in creating the high resolution (1m, 5m) and low resolution (1h, 1d, 27d) versions of OMNI. Further details on our processing steps are available here (low resolution) or here (high resolution). A comprehensive path to all SPDF-resident heliospheric data is available here .
