Acknowledgment
The authors wish to acknowledge the
many contributions to this experiment -
its planning, implementation, and
execution - by their colleagues not only
in NASA but more particularly in the
U.S. Department of Agriculture (USDA)
and in the National Oceanic and Atmo-
spheric Administration (NOAA) of the
U.S. Department of Commerce. This is
truly a joint venture among the three
agencies, and many have played important
roles in bringing the experiment to its
present state.
