AIM/CDE dust grain impact data

ResourceID
spase://NASA/NumericalData/AIM/CDE/PT1D

Description

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.
