Summary
Abstract:
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.
This experiment is designed to measure the full three-dimensional
distribution of suprathermal electrons and ions at energies from a few
eV to over several hundred keV on the WIND spacecraft. Its high
sensitivity, wide dynamic range, and good energy and angular
resolution make it especially capable of detecting and characterizing
the numerous populations of particles that are present in
interplanetary space at energies above the bulk of the solar wind
particles and below the energies typical of most cosmic rays.
Data consists of ion moments, energy spectra, electron spectra,
electron and ion omni directional energy spectra. Data are available
from SSL at University of California, Berkeley
(http://sprg.ssl.berkeley.edu/wind3dp/esahome.html) and at the NSSDC
CDAWeb (http://cdaweb.gsfc.nasa.gov/cdaweb/)

WARNING: EP TOMS started experiencing calibration problem since 2002. For data beginning in year 2000, the calibration has been stabilized relative to NOAA-16 SBUV/2 in the equatorial zone. Because of continuing changes in the optical properties of the front scan mirror that are not well understood, data are showing a latitude dependent error that cannot be corrected by a simple calibration correction. The calibration appears to be stable near the equator. But by 50 degrees latitude, there is now a -2% to -4% error in TOMS, a bit larger in the northern hemisphere than in the southern hemisphere. Because of this error, data since 2002 should NOT be used for trend analysis
