The study object and problem in geosciences are characterized by longtime, large scale, and big dimension. These studies need to be carried out not only in the laboratory but also on the spot with big range, the longtime series observed data. Facilities and instrumentation for observation, experimentation, analysis, and computation are essential to carrying out research in all fields of the geosciences. The facilities plan (19992003) is the first “facilities plan” in GEO history and it described existing and planned facilities in the Earth environmental observation systems, calculation system, laboratory system and sample and data access systems. The existing facilities which need to be maintained and improved, and planned ones to be used in Earth environmental observing systems as well as the present implementation work are introduced.
