Meteor Modeling

About 100 tons of meteoroids enter the Earth's atmosphere every day.  Even though most of these meteoroids are very small (less than a milligram), they are travelling very fast, between 12 and 72 km/sec.  Because of their fast speeds, these meteoroids pose a potential threat to spacecraft.  The current models of the masses and velocities of the meteroid population around Earth contain large uncertainties.  A major reason for this is that the models describing how meteoroids ablate when entering the Earth's' atmosphere require many assumptions and contain large errors.  I use data taken from some of the largest and most sensitive radars in the world (PFISR, JRO, ALTAIR) and high speed cameras to investigate large sample sizes of meteors and improve the current models, which will then improve our understanding of the overall meteoroid population.
