New methodology to determine the terminal height of a fireball

摘要: Abstract Despite ablation and drag processes associated with atmospheric entry of meteoroids were a subject intensive study over the last century, little attention was devoted to interpret observed fireball terminal height. This is key parameter because it not only depends on initial mass, but also bulk physical properties hence their ability ablate in atmosphere. In this work we have developed new approach that tested using heights by Meteorite Observation Recovery Project operated Canada between 1970 1985 (hereafter referred as MORP). We then compare them calculation made. Our results clearly show methodology able forecast degree deepening Earth’s Then, has important applications predicting impact hazard from cm- meter-sized bodies are represented, part, MORP bolide list.
