AIM/CDE dust grain impact data

Published by SPDF, UCOLO | National Aeronautics and Space Administration | Catalog Last Checked: November 04, 2026 at 12:55 AM | Dataset Last Updated: November 03, 2026
AIM/CDE (Cosmic Dust Experiment) data are available as Levels 1 and 2 daily netCDF files. L1 data contains, for each dust grain impact, a time tag, pulse height data, a number of electrons released by the impact, and engineering and housekeeping data. L2 data adds the mass of the impacting particle and spacecraft location at time of impact. Future L3 and L4 products will add total mass impacting per orbit and impact rates (L3) and mass correlation with CIPS total particle mass and Polar Mesospheric Cloud brightness.
