Solar Wind Experiment (SWE) on WIND

The main purpose of the Wind spacecraft is to measure the incoming
solar wind, magnetic fields and particles, although early on it will
also observe the Earth's foreshock region. Wind, together with
Geotail, Polar, SOHO, and Cluster projects, constitute a cooperative
scientific satellite project designated the International Solar
Terrestrial Physics (ISTP) program which aims at gaining improved
understanding of the physics of solar terrestrial relations.

The Solar Wind Experiment (SWE) is a collaborative effort of Goddard
Space Flight Center (GSFC), University of New Hampshire (UNH), and
Massachusetts Institute of Technology (MIT). The WIND SWE (Solar Wind
Experiment) instrument includes 2 Faraday cup ion detectors provided
by the MIT Center for Space Research. The Faraday cup detectors were
activated on 12 November 1994, and have operated perfectly since
then. The Faraday cups provide measurements of the solar wind protons
and alpha particles at energy/charge up to 8 keV, and MIT is
responsible for analysis of the Faraday cup data.

SWE plots and data are available from MIT:

and from the Polar-Wind-Geotail (PWG) Data Archive
(ftp://pwgdata.gsfc.nasa.gov/pub/00readme.html) and at the NSSDC
CDAWeb (http://cdaweb.gsfc.nasa.gov/cdaweb/)

Solar wind proton and alpha particle parameters are available at full
