Is there a CESM1 Paleo Users Guide under development? I am currently in the process of modifying CESM to simulate early (4 Ga-600 Ma) Earth, Mars, Venus etc., and a current step would be to create tools for configuring deep time climate simulations within the ordinary B component set framework, much like I've done with CCSM3 in the past. I'd love some guidance on the basics, even just the list of input files that might need to be modified and notes on unusual formats. I'd be glad to share any tools I develop.
