Scientific paper

From May 22, 1981, to July 11, 1991, the ongoing NASA/JSC Cosmic Dust Program has collected dust in the stratosphere between 17-19 km altitude, generally over the western U.S. up to Alaska, with excusions along the Pacific coast down to the equator. Each particle is identified by a SEM microscope image, an energy dispersive spectrum, several optical properties, and its size and is listed in the Cosmic Dust Catalogs 1-14 and in Cosmic Dust Couriers. The curator's office has established criteria to identify the particles but these identifications are not definitive. Still, 10 years of collective experience show that the 'cosmic' label is used consistently and confirmed by subsequent petrological and chemical analyses, for all that rare errors occur. It is possible to use this database to study intra- and interannual trends in the abundances of interplanetary dust particles.
