Supplementary material: data availability compiling the database and our analytical results

Files used in this study: (i) "IDP_Neve_Concordia_CRPG_MNHN_GFénisseEtAl_EPSL.xlsx", a snow mass compilation from clean snow at the CONCORDIA station (Dome C, Antarctica); (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; (vi) "ReferencesTable_3HeETFlux_GFénisseEtAl_EPSL.xlsx", a database of light noble gas measurements in Antarctica MMs. This dataset of He vs. MM mass is used here to convert ³He concentrations into dust abundances.
