    • ACE Solar Isotope Spectrometer (SIS) 256-sec Level 2 Data

    Metadata Updated: February 6, 2026

    ACE Solar Isotope Spectrometer (SIS) 256-sec intensities and count rates, for each of 14 elements (He,C,N,O,Ne,Na,Mg,Al,Si,S,Ar,Ca,Fe,Ni). in each of 8 energy bins. Overall energy ranges covered go from 3.4-41 MeV/n for helium to 10.5-168 MeV/n for iron. These are calibrated science quality data. The data are accessible via ftp in HDF and CDF from the ACE Science Center and CDAWeb, respectively, and in ASCII format from the value-added interfaces at those sites. The "parameter keys" given below are as used by CDAWeb.
