IMF Values

The CEDAR Database contains hourly Interplanetary Magnetic Field (IMF) and solar plasma data from various satellites from 27 November 1963 to within about 6 months of the present. These can be obtained via the CEDAR Database (click on 'Data Services', 'Get/plot data' and proceed with 'Select an Instrument', 'Interplanetary Mag Fld and Solar Wind' about 3rd page down after the IS radars). One minute IMF data for World Day campaign periods are available from 13 April 1983 to 19 January 1988. Some other data sources are:

hourly IMF and plasma data (1963-present) at the National Space Science Data Center
2 min IMP MIT plasma data (1973-present) at MIT
ISTP key parameters of IMF and solar plasma data from Wind (11/94-present), IMP-8 (10/73-present) and ACE (8/97-present) from http://nssdc.gsfc.nasa.gov/space/ndads/spycat.html
Definitive WIND magnetometer (PI R. Lepping) 3-sec, 1-min, 1-hour data from Nov 1994-Jul 1999. In ascii at ftp site ftp://nssdcftp.gsfc.nasa.gov/spacecraft_data/wind/mag. Will also be available via CDAWeb.
Last 3 months of IMF and solar plasma data from WIND and (IMF from MFI and plasma data from SWE) and near real-time data
Last 3 months and real-time IMF and solar plasma data from ACE (IMF from MAG and plasma data from SWEPAM) at ACE lists.
