AB: Several recent studies have shown decadal variation in Top of Atmosphere (TOA) shortwave (SW) reflected and longwave (LW) thermal infrared emitted fluxes from satellite, as well as SW insolation at the surface. This paper will show the variations found in both ERBS and CERES satellite radiation budget data, including recent algorithm and calibration improvements in each time series. Results will be shown both for tropical as well as global mean variations, and compared to other satellite flux estimates including ISCCP FD, and AVHRR and HIRS Pathfinder datasets. Global results will be compared against independent global ocean heat storage data. The results show significant changes that are consistent with ocean heat storage variability through 2002. Interannual variations are large and suggest a tight coupling of changes in net cloud radiative forcing and ocean heat storage. Implications are considered for studies of cloud feedback in climate models, as well as for design of future climate observing systems and the climate change signals they will be required to unambiguously resolve.
