  There is an opportunity to advance both solar system and extrasolar planetary
studies that does not require the construction of new telescopes or new
missions but better use and access to inter-disciplinary data sets. This
approach leverages significant investment from NASA and international space
agencies in exploring this solar system and using those discoveries as "ground
truth" for the study of extrasolar planets. This white paper illustrates the
potential, using phase curves and atmospheric modeling as specific examples. A
key advance required to realize this potential is to enable seamless discovery
and access within and between planetary science and astronomical data sets.
Further, seamless data discovery and access also expands the availability of
science, allowing researchers and students at a variety of institutions,
equipped only with Internet access and a decent computer to conduct
cutting-edge research.
