Observations of weather and climate yield demonstrated societal benefits, and have been officially part of U.S.
government activities since Jefferson. Observing sensor networks contribute to real-time warnings of extreme weather,
and to long-term analysis of endemic disease. To learn more about netcentric technologies and their role in observing
sensor networks, the National Oceanic & Atmospheric Administration (NOAA) National Weather Service (NWS) and
the American Institute of Aeronautics and Astronautics (AIAA) organized a seminar that examined System-of-Systems
(SOS), Enterprise Architecture (EA) and Internet Protocol version 6 (IPv6) concepts, using two NOAA programs, the
Global Earth Observation Integrated Data Environment (GEO-IDE) and the Integrated Ocean Observing System (IOOS),
as examples. Further analysis of the seminar material shows the interrelationship of SOS and EA, with the enabling
capability of IPv6 and the framework of a Service-Oriented Architecture (SOA), can help NOAA organize sensor
systems-of-systems on a global scale in support of the Global Earth Observing System-of-Systems (GEOSS).
