On the Full and Open Exchange of Scientific Data    To address
issues of the global environment, it is essential to have a
sound scientific understanding of the Earth and its constituent
elements. The research required to attain that understanding
vitally depends on observations and processed data on all
aspects of the system and from all parts of the globe. Such
research has been facilitated by an international system of full
and open exchange of scientific data and information. In May
1995, however, a proposal will be considered by the Congress of
the World Meteorological Organization (WMO), originating in its
working group on commercialization. This proposal would restrict
the availability of environmental data, information, and

to conduct research on global- or regional-scale problems.
Current international practices guaranteeing the full and open
exchange of scientific data should, if anything, be expanded,
not restricted.  The Need for Ful
