2.3.1 spase://NASA/NumericalData/AIM/CDE/PT1D AIM/CDE dust grain impact data 2020-12-05T20:54:15Z 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.
