Improved representation of solar variability in climate models

How much do solar cycle variations influence our climate system? Could the rising Earth temperatures due to anthropogenic effects partly be compensated by a reduction of solar forcing in the future? These questions have been in the focus of climate research for a long time. In order to answer these questions as precisely as possible, it is required to know the fluctuations of solar forcing on the timescale of the 11-year sunspot cycle as precisely as possible in order to use these as input param
