Earth climate sciences involve complex coupling between the Sun, the atmosphere, landmasses, and the oceans. Natural forcings, such as volcanic eruptions and the variability of solar irradiance and particles can have large local effects on the Earth's dynamical system. One substantial uncertainty in our understanding of the Sun-Earth system is the absolute level of the Earth's radiation budget, in particular the precise quantification of the Earth's radiation imbalance. This session invites reports on recent observational results from the ISS/SOLAR instruments SOLSPEC and SolACES, SORCE, PICARD/PREMOS, NORSAT1/CLARA, CERES, ISS/TSIS, as well as future missions such as EarthCARE, CLARREO, and others. Results from global and regional climate modeling discussing the effects of past and possible future variations in solar variability, ozone, water vapor, clouds, and aerosols, anthropogenic forcing, and the Earth's radiation budget are welcome too.
