We present the CMIP7 solar forcing dataset and its validation both for the effects of solar irradiance and particle forcing. In particular we present the results from first simulation runs that use the new CMIP7 as well as the previous CMIP6 dataset for the period 2002-2012, covering two solar maxima and a deep solar minimum. Specifically, we present simulation runs carried out with the chemistry-climate models WACCM, SOCOL, EMAC, ICON and KASIMA to determine the response to the solar SSI and particle forcing. The performance of the CMIP7 recommendations with respect to atmospheric radiative heating and composition will be evaluated both compared to the CMIP6 recommendations, and to satellite observations of atmospheric trace gases. The different responses and their implications will be discussed.
