Is there any prescribed aerosol concentration datasets for concentration-driven models?

[icefranklin]

We are trying to use concentration-driven models, but there is no prescribed aerosol concentration datasets available, will CMIP7 group provide such datasets? Or do we need to generate by ourselves?

Hello, do you mean tropospheric aerosol concentrations? CMIP7 provides tropospheric aerosol optical properties here and stratospheric aerosol optical properties here .
