Appendixes

The following appendixes provide short summaries of the deliberations of the working groups on the four scientific areas of the U.S. Global Change Research Program (USGCRP) and on the role of the National Aeronautics and Space Administration (NASA), Mission to Planet Earth/Earth Observing System (MTPE/EOS) and EOS Data and Information System programs in the context of the overall program. These documents were written by the designated working group chairs and reflect their sense of the views of working group participants, further illuminated by extensive plenary discussions in the course of the workshop. These documents provide a window into the information, analysis, and discussion drawn on by the committee in formulating its conclusions and are presented here to provide a background for the preceding report. However, they do not represent approved conclusions or recommendations of the workshop or of the responsible committee. The chairs of the six working groups are also preparing a set of more complete interim working documents that describe their deliberations in more detail and will be used as critical input to the second phase of the comprehensive review of the USGCRP.
