Daily Dust Influx at Earth Inferred from Accretion Rates and Orbital Flux Models

This paper examines Tonnes per day of interplanetary material accreted by Earth, compared across satellite, radar and atmospheric-chemistry estimates. Using only published input values and transparent formulae, the calculation obtains the following headline results: love_brownlee_daily_influx_tonnes = 109.5; flux_model_daily_influx_tonnes = 52.9; plane_2012_central_daily_tonnes = 43; ratio_LB_to_plane = 2.55; collecting_area_with_focusing_m2 = 2.04026e+14; adopted_range_tonnes_per_day = [20.0, 110.0]. The satellite-based estimate corresponds to about one hundred and ten tonnes per day and the flux-model recomputation to about fifty-three tonnes per day, while atmospheric metal-layer chemistry favours a lower central value near forty-three tonnes per day; the factor of roughly two and a half between the highest and lowest is the live discrepancy. The method, inputs and limitations are stated in full so that any reader can reproduce or rescale every number from the deposited calculation script. Agreement and disagreement with independent published estimates are reported at their actual size, and the conclusions are limited to what the budget arithmetic supports.
