NSSDC OMNI Data Set Updated
Volume 11, Number 2, June 1995
By Emily Greene
NSSDC's OMNI data set of hourly solar wind magnetic field and plasma parameters, energetic particle fluxes, and geomagnetic and solar activity indices has recently been updated in all its parameters. All spacecraft data added came from IMP 8 (Lepping, Lazarus, Armstrong). In addition, the 1963-1972 part of OMNI, long available on the OMNItape, has also been made part of the on-line version of OMNI. New time spans for the various parameters are as follows:
This data set underlies the long-available NODIS/OMNI as well as the recently developed and enthusiastically received OMNIWeb.
- Magnetic field: 63/331 - 94/179.
- Plasma: 63/331 - 94/365.
- Energetic particles: 73/001 - 94/346.
- Kp, C9, and Rz: 63/306 - 95/031.
- Dst: 63/306 - 92/366.
