Phase I of the ESE has been comprised of focused, free-flying satellites,
Space Shuttle missions, and various airborne and ground-based studies.
Phase one has provided global measurements of major Earth system
components. Their purpose was to improve our knowledge of basic
processes prior to the Earth Observing System (EOS) era. These include the
currently operating
Upper Atmosphere Research Satellite (UARS), which confirmed the
anthropogenic origin of ozone-depleting substances
(http://umpgal.gsfc/nasa.gov/),
TOPEX/Poseidon, which is detecting variations in sea level worldwide
(http://topex-www.jpl.nasa.gov/),
