The SWICS/MASS/STICS (SMS) Instrument Package on WIND

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 SWICS/MASS/STICS (SMS) instrument package consists of measurements from the Solar Wind Ion Composition Spectrometer (SWICS), the High MASS Resolution Spectrometer (MASS) and the SupraThermal Ion Composition Spectrometer (STICS) to study the following issues: - solar abundances - solar wind acceleration - physical processes in the solar atmosphere - physical properties of the lower corona - solar wind kinetic properties - production of suprathermal ions - interplanetary acceleration mechanisms - pick-up and acceleration processes of interstellar and lunar neutrals SWICS data consists of: - alpha velocity - C/O abundance - C and O ionization temperature STICS data consists of: - alpha velocity - rates (counts/spin) - proton and alpha matrix rates (counts/spin) - He+ and O+ matrix rates (counts/spin) SMS data are available from UMD space.umd.edu/wind/Data.html and from the Polar-Wind-Geotail (PWG) Data Archive (ftp://pwgdata.gsfc.nasa.gov/pub/00readme.html) and at the NSSDC CDAWeb (cdaweb.gsfc.nasa.gov/cdaweb/)
