The solar forcing dataset prepared for the 6th round of the Coupled Model Intercomparison Project (CMIP6) has been used extensively in climate model experiments. Recently, an International Space Science Institute (ISSI) Working Group was established to revisit the solar forcing recommendations in order to define a roadmap for building a revised solar forcing dataset for the upcoming 7th round...
This presentation will provide an overview of the next generation ozone forcing database in support of the Coupled Model Intercomparison Project phase 7 (CMIP7). Tropospheric and stratospheric ozone changes are key drivers of climate change and need to be accounted for in climate model simulations that aim at understanding past and future climate responses to anthropogenic emissions of...
Polar winter descent of reactive nitrogen (NOy) produced by energetic particle precipitation (EPP) in the mesosphere and lower thermosphere affects polar stratospheric ozone by catalytic reactions. This, in turn, may have implications for regional climate via radiative and dynamical feedbacks. NOy observations taken by the MIPAS/Envisat instrument during 2002--2012 have provided observational...

The Icosahedral Non-hydrostatic model framework is the open-source numerical weather prediction model and climate model developed by the German Weather Service DWD and the Max-Planck Institute of Meteorology. A consolidated climate setup with interactive ocean, land surface and atmosphere is currently being developed and tested. However, while ICON in its base setup includes varying solar TSI...
Direct measurements of solar irradiance variations began in the late 1970s.
Recovery of irradiance over earlier periods is only possible with appropriate models.
Such reconstructions require solid understanding of the physical processes driving the irradiance fluctuations as well as information on the past changes of the magnetic activity of the Sun.
The magnetic field emerging at the...
Reconstructions of energetic electron precipitation (EEP) and the atmospheric ionization it produces are important for state-of-the-art chemistry-climate models, which aim to model the climate impacts of EEP. The current version of the Coupled Model Inter-comparison Project, CMIP6, includes a reconstruction of EEP-induced ionization based on a parameterization dependent on geomagnetic Ap...
A new dataset has been provided for CMIP7, to model the ion pair production due to mid-energy electron precipitation.
The data set has been calculated using an updated version of the CMIP6 electron flux model and an atmospheric ionization parameterization (Fang et al., Geophys. Res. Lett., 37, L22106, doi:10.1029/2010GL045406, 2010). The electron flux model is fit to equivalent isotropic...
In order to determine the effect of energetic particle forcing on the Earth’s atmosphere over decadal timespans it has been necessary to develop models of energetic electron precipitation (EEP) based on long time-series geomagnetic indices. This has been done using the geomagnetic index, Ap, and recommended for use as one of the solar forcing factors in the Coupled Model Intercomparison...
