The interplanetary dust complex is described by several dynamic populations of particles. New populations are tested against diverse observations. The new populations differ essentially from those adopted in earlier meteoroid models and are tied to long-term dynamics of the interplanetary dust. The data set used for validation of the model include infrared emission observations with COBE DIRBE instrument and impact counts with the dust detectors aboard Galileo and Ulysses spacecraft. It is found that under reasonable assumptions about sources, dynamics and composition of the interplanetary dust both remote observations and in-situ measurements can be reproduced by a combination of the new populations quite well.
