ACE Solar Isotope Spectrometer (SIS) 1-Hour Level 2 Key Parameter Data

Published by NASA Space Physics Data Facility (SPDF) Data Services;SRL ACE Science Center;ASC | National Aeronautics and Space Administration | Catalog Last Checked: May 18, 2026 at 03:47 PM | Dataset Last Updated: May 11, 2026
ACE Solar Isotope Spectrometer (SIS) hourly 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.
