Technology for monitoring global change

Multiinstrumented earth-science platforms currently being planned for both LEO and GEO positions will furnish data for the compilation of systematic and intercorrelated information that is suitable for the treatment of interdisciplinary questions concerning atmospheric, oceanic, hydrological, geological, and biological changes of an either natural or anthropogenic nature. Attention will be given in these observational campaigns to such essential earth variables as atmospheric pressure, rainfall/snowfall, vegetation cover, soil nutrient cycles, sea surface temperatures, ocean circulation, and ocean biological productivity.
