ACE Real-Time Solar Wind Data
ACE Real-Time Solar Wind (RTSW) Data from NOAA's Space Weather Prediction Center (SWPC) provides up to an hour's advance warning of unusual solar activity, such as solar flares and coronal mass ejections, which can cause geomagnetic storms.
Four ACE instruments supply data to NOAA's SEC for RTSW processing. The instruments are:
- EPAM - Energetic Ions and Electrons
- MAG - Magnetic Field Vectors
- SIS - High Energy Particle Fluxes
- SWEPAM - Solar Wind Ions
NOAA's Space Weather Prediction Center provides online access only to the most-recent ACE RTSW data. They do not provide a mission-length archive of these data to the public. The ACE Science Center does maintain an archive of these data and the ACE team recognizes the potential use of this archive for enabling or testing of various space weather models. However, concerns remain about the preliminary nature and primitive calibrations used to process these data. Therefore the ACE team has decided to make this RTSW data archive available on the web by request, via a password.
ACE RTSW Data Archive: Contact the ASC via email (address below) to obtain password access to the archive.
Higher-quality (verified by the instrument teams) ACE solar-wind and magnetometer data are available from the ACE Level 2 Data website.
