Contributing Authors: G. Bodeker (New Zealand), O. Boucher (UK, France), W.D. Collins (USA), T.J. Conway (USA), E. Dlugokencky (USA), J.W. Elkins (USA), D. Etheridge (Australia), P. Foukal (USA), P.Expand
A new, lower value of total solar irradiance: Evidence and climate significance
[1] The most accurate value of total solar irradiance during the 2008 solar minimum period is 1360.8 ± 0.5 W m−2 according to measurements from the Total Irradiance Monitor (TIM) on NASA's SolarExpand
Reconstruction of solar irradiance since 1610: Implications for climate change
Solar total and ultraviolet (UV) irradiances are reconstructed annually from 1610 to the present. This epoch includes the Maunder Minimum of anomalously low solar activity (circa 1645-1715) and theExpand
Evolution of the Sun's Spectral Irradiance Since the Maunder Minimum

  • 15 August 2000
Because of the dependence of the Sun's irradi- ance on solar activity, reductions from contemporary levels are expected during the seventeenth century Maunder Min- imum. New reconstructions ofExpand
Efficacy of climate forcings
[1] We use a global climate model to compare the effectiveness of many climate forcing agents for producing climate change. We find a substantial range in the “efficacy” of different forcings, whereExpand
Modeling the Sun’s Magnetic Field and Irradiance since 1713
We use a flux transport model to simulate the evolution of the Sun's total and open magnetic flux over the last 26 solar cycles (1713-1996). Polar field reversals are maintained by varying theExpand
Solar radiative output and its variability: evidence and mechanisms
Abstract.Electromagnetic radiation from the Sun is Earth’s primary energy source. Space-based radiometric measurements in the past two decades have begun to establish the nature, magnitude andExpand
The Sun's total irradiance: Cycles, trends and related climate change uncertainties since 1976
A composite record of the Sun's total irradiance compiled from measurements made by five independent space-based radiometers since 1978 exhibits a prominent 11-year cycle with similar levels duringExpand
Solar EUV Experiment (SEE): Mission overview and first results
[1] The Solar EUV Experiment (SEE) is one of four scientific instruments on the NASA Thermosphere Ionosphere Mesosphere Energetics Dynamics (TIMED) spacecraft, which has been simultaneously observingExpand
Climate Forcing by Changing Solar Radiation
Abstract By how much does changing radiation from the sun influence the earth’s climate, presently and in the recent past, compared with other natural and anthropogenic processes? Current knowledgeExpand
