Short summary
Meteoroids entering the atmosphere produce trails of ionized particles which can be detected with radar. The weakest ones are called underdense (the most common), the strongest are called overdense, and intermediate ones are transitional. Meteor radar signatures are used to determine atmospheric parameters like temperature and winds. We present new results which show the effect of ozone on the transitional trail lifetimes, which may eventually allow radar to measure mesospheric ozone.
