Interplanetary dust model: from micron-sized dust to meteors

New populations of interplanetary dust are proposed for the ESA meteoroid model. Formulation of the new model extends earlier meteoroid models and is now tied to orbital evolution of the interplanetary dust. To validate the new model, infrared emission observations with COBE DIRBE instrument, impact counts with the dust detectors aboard Galileo and Ulysses spacecraft, and the radar meteors monitored with AMOR are used. Incorporation of meteor data in the model is discussed.
