It could be further developed to be integrated with GIS and other databases, such as the Forest Resource Information System, and with simulation and modelling capabilities to assist in the planning and definition of forestry policies.

Two and three dimensional mathematical modelling programmes have been devised.

Aylward, quot Modelling the effects of thermospheric winds on satellite orbits quot , paper presented at ESTEC Symposium on Environment Modelling for Space Based Applications, Noordwijk, Netherlands, 18 20 September 1996.

Ozone, greenhouse gases and air pollution distribution modelling (above big cities)

Stronger ties between the modelling and measurement communities must be fostered.

A special focus of this global modelling is the Asia Pacific region.

This modelling work is complementary to that of the University of Kent.

Other than the modelling of the present debris population, the long term modelling requires assumptions describing the future space flight activities, including the debris generation mechanisms, in terms of, for example

Habitat modelling based on satellite maps is now being implemented for selected species.

GRID Arendal also assists in the development of the coastal environmental information modelling system.

These include ground based equipment, meteorological stations, stations for balloon launching, stations for rocket launching, an atmospheric chemistry laboratory, stations for ionospheric research, and a laboratory and software for climate modelling, in particular Indonesian climate modelling.

IADC also develops cooperative research projects associated with measuring and modelling the space debris environment.

The University of Kent continues its work on retrieved surface analysis and hypervelocity impact modelling.
