Investigation of the interplanetary dust cloud is characterized by
contributions from quite different methods and fields, such as
research on zodiacal light, meteors, micrometeoroids, asteroids,
and comets. Since the earth's environment and interplanetary space
became accessible to space vehicles these interrelations are
clearly evident and extremely useful. Space measurements by
micrometeoroid detectors, for example, provide individual and
eventually detailed information on impact events, which however are
limited in number and therefore restricted in statistical
significance. On the other hand, zodiacal light measurements
involve scattered light from many particles and therefore provide
global information about the average values of physical properties
and spatial distribution of interplanetary grains. Additional
knowledge stems from lunar samples and from dust collections in the
atmosphere and in deep sea sediments. All these sources of
complementary information must be put together into a synoptical
synthesis. This also has to take into account dynamical aspects and
the results of laboratory investigations concerning physical
properties of small grains. Such considerable effort is not merely
an academic exercise for a few specialists interested in the solar
dust cloud. Since this same cloud exclusively allows direct in-situ
acess to investigate extraterrestrial dust particles over a wide
range of sizes and materials, it provides valuable information for
realistic treatment of dust phenomena in other remote cosmic
regions such as in dense molecular clouds, circumstellar dust
shells, and even protostellar or protoplanetary systems.
