(ii) "Calibration_of_He_concentration_inFurnace_GFénisseEtAl_EPSL.xlsx", the furnace calibration for He measurements;
(iii) "HeResults_IDPsMMs_GFénisseEtAl_EPSL.xlsx", the He isotopic compositions and total masses of cosmic dust, categorized by size range, from the CONCORDIA snow;
(iv) "ETMassFluxSynthesis_GFénisseEtAl_EPSL.xlsx", ET mass comparisons from collection, He method and CABMOD-ZoDy modeling.
(v) "Database_IDPs&MMs_He&Ne_GFénisseEtAl_EPSL.xlsx", an exhaustive database containing all published light noble gas data (³He, ⁴He, and ²⁰Ne) measured in IDPs and MMs collected in the stratosphere and Antarctica;
