The Earth's atmosphere acts as a filter that modifies the population of meteoroids reaching the surface. In this seminar, I will present an analysis comparing the meteoroid flux at the top of the atmosphere with the meteorite flux, using data from the FRIPON and 18 similar networks encompassing observations from over 39 countries. Our findings reveal statistically significant differences between these populations, suggesting that atmospheric entry processes and thermal disintegration in near-Earth space affect meteoroid survival. We also examine cosmic ray exposure ages of carbonaceous chondrites and assess orbital clustering amongst impact and near-Earth object populations to better understand meteoroid sources and evolutionary pathways. These insights have implications for refining meteoroid production, delivery, and meteorite source region models.
