<P> An imbalance must show in something on Earth warming or cooling (depending on the direction of the imbalance), and the ocean being the larger thermal reservoir on Earth, is a prime candidate for measurements . </P> <P> Earth's energy imbalance measurements provided by Argo floats have detected an accumulation of ocean heat content (OHC). The estimated imbalance was measured during a deep solar minimum of 2005 - 2010 to be 0.58 ± 0.15 W / m2 . This level of detail cannot be inferred directly from measurements of surface energy fluxes, which have combined uncertainties of the order of ± 17 W / m2 . </P> <P> Several satellites indirectly measure the energy absorbed and radiated by Earth and by inference the energy imbalance . The NASA Earth Radiation Budget Experiment (ERBE) project involves three such satellites: the Earth Radiation Budget Satellite (ERBS), launched October 1984; NOAA - 9, launched December 1984; and NOAA - 10, launched September 1986 . </P> <P> Today NASA's satellite instruments, provided by CERES, part of the NASA's Earth Observing System (EOS), are designed to measure both solar - reflected and Earth - emitted radiation . </P>

100 of the energy entering the earth's atmosphere comes from the sun
