A new, lower value of total solar irradiance: Evidence and climate significance
Greg Kopp,Judith Lean +1 more
TL;DR: 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 Solar Radiation and Climate Experiment (SORCE) and a series of new radiometric laboratory tests as discussed by the authors.
Book ChapterDOI
Sorce contributions to new understanding of global change and solar variability
TL;DR: For example, the Solar Radiation and Climate Experiment (SORCE) as mentioned in this paper monitors both total and spectral irradiance with significantly reduced uncertainty and increased re- peatability, especially on long time scales.
Journal ArticleDOI
Accurate monitoring of terrestrial aerosols and total solar irradiance: Introducing the Glory mission
Michael I. Mishchenko,Brian Cairns,Greg Kopp,Carl F. Schueler,Bryan A. Fafaul,James Hansen,R. Hooker,Tom Itchkawich,Hal Maring,Larry D. Travis +9 more
TL;DR: The NASA Glory mission as discussed by the authors is intended to facilitate and improve upon long-term monitoring of two key forcings influencing global climate by flying two state-of-the-art science instruments on an Earth-orbiting platform.
Journal ArticleDOI
