Preliminary, 5-min averages (from AC_K0_SWE dataset). Parameters include proton density, temperature (radial component) and flow speed, flow velocity vector in GSE, GSM and RTN coordinates, and alpha to proton density ratio. AMDA presents temperature in eV.

However, to avoid confusion and misunderstanding, it is recommended that users consult with the appropriate ACE team members before publishing work derived from the data. The ACE team has worked hard to ensure that the level 2 data are free from errors, but the team cannot accept responsibility for erroneous data, or for misunderstandings about how the data may be used. This is especially true if the appropriate ACE team members are not consulted before publication. At the very least, preprints should be forwarded to the ACE team before publication. density swp_n Solar Wind Proton Number Density, scalar phys.density;phys.atmol.ionStage Np is the proton number density in units of cm-3, as calculated by integrating the ion distribution function. cm^-3 TimeSeries 0.0 200.0 -1.0E31 Proton Moment NumberDensity v_bulk swp_v Solar Wind Bulk Speed phys.veloc;phys.atmol.ionStage Vp is the solar wind proton speed, or more generally just the solar wind (bulk) speed.
