| 英文摘要: | Combining satellite data, atmospheric reanalyses, and climate model simulations, variability in the net downward radiative flux imbalance at the top of Earth's atmosphere (N) is reconstructed and linked to recent climate change. Over the 1985-1999 period mean N (0.34 ± 0.67Wm-2) is lower than for the 2000-2012 period (0.62 ± 0.43Wm-2, uncertainties at 90% confidence level) despite the slower rate of surface temperature rise since 2000. While the precise magnitude of N remains uncertain, the reconstruction captures interannual variability which is dominated by the eruption of Mount Pinatubo in 1991 and the El Niño Southern Oscillation. Monthly deseasonalized interannual variability in N generated by an ensemble of nine climate model simulations using prescribed sea surface temperature and radiative forcings and from the satellite-based reconstruction is significantly correlated (r∼0.6) over the 1985-2012 period. Key Points Earth's net radiative imbalance during 1985-2012 is 0.47 ±0.67 Wm-2 Observed variability in Earth's radiation budget is captured by simulations Slower surface warming but increased radiative heating from 1985-1999 to 2000s © 2014.
