  skos:definition """The Clouds and the Earth s Radiant Energy System (CERES)
 experiment is one of the highest priority scientific satellite
 instruments developed for EOS. CERES products include both
 solar-reflected and Earth-emitted radiation from the top of the
 atmosphere to the Earth's surface. Cloud properties are
 determined using simultaneous measurements by other EOS
 instruments such as the Moderate Resolution Imaging
 Spectroradiometer (MODIS). Analyses of the CERES data, which
 build upon the foundation laid by previous missions such as the
 Earth Radiation Budget Experiment (ERBE), will lead to a better
 understanding of the role of clouds and the energy cycle in
 global climate change.

 CERES instruments were launched aboard the Tropical Rainfall
 Measuring Mission (TRMM) in November 1997 and on the EOS Terra
 satellite in December 1999. Two additional instruments will fly
 on the EOS Aqua spacecraft in 2002. Multiple satellites are
 needed to provide adequate temporal sampling since clouds and
 radiative fluxes vary throughout the day. The first 24 months
 of CERES data collected on both TRMM and Terra demonstrate that
 the CERES instruments are substantially improved over the ERBE
 instruments. The CERES data show lower noise, improved ties to
 the ground calibration in absolute terms, and smaller fields of
 view. CERES instrument calibration stability on TRMM and Terra
 is typically better than 0.2%, and calibration consistency from
 ground to space is better than 0.25%. Onboard calibration
 sources provide traceability of the measurements to the
 International Temperature Scale of 1990 at the 0.2% level. Such
 levels of accuracy have never before been achieved for rad!
 iation budget instruments.
