#Omniweb data code

See This presentation reviews briefly the assumptions behind the time shifts and discusses the parameters in the records of the draft 1-min OMNI data set, the criteria for assigning parameter values for a given minute when data are available for that minute from multiple sources, and the cross-normalizations among sources. The web services consists of OMNI data (spacecraft-interspersed, near-Earth solar wind data) spacecraft-specific data sets (near 1 AU, including near-Earth) including ACE, Geotail, IMP-8, IMP6&7, Wind, Explorer 33&35, Genesis. These spacecraft-specific data sets were presented at the December 2005 AGU Meeting. OMNIWeb at the Space Physics Data Facility (SPDF) Hourly-averaged near-Earth solar wind magnetic field and plasma, etc.

#Omniweb data code

The minute averages are based on 15 or 16 sec IMF data, and 1-min (approximately) plasma data, that have been shifted to (14, 0, 0 Re, GSE) using Weimer et al minimum variance analysis (MVA) code run against the IMF data. Input to this 1-min OMNI are spacecraft-specific 1-min-resolution field-plasma-merged data sets from ACE, Wind and IMP 8. We report creation of a draft 1-min-resolution, multi-source OMNI data set covering 1998. But its value in the coupling studies has deteriorated because most such studies now require higher resolution solar wind data. For 30 years, the hourly resolution, periodically updated OMNI data set, a multi-source compilation of near- Earth solar wind magnetic field and plasma data and other data, has been used in many studies of solar wind variations and of solar wind-magnetosphere coupling.
