Constraining a Radiative Transfer Model with Satellite Retrievals: Contrasts between cirrus formed via homogeneous and heterogeneous freezing and their implications for cirrus cloud thinning Abstract. The efficacy of the climate intervention method known as cirrus cloud thinning (CCT) is difficult to evaluate in climate models, largely due to uncertainties governing the relative contribut...

It's been such a crazy week, I haven't had time to post about it yet...but yeah, we have a new paper out 🎉 in @aguadvances.bsky.social about the Pliocene - the last time Earth experienced CO2 level like we have now. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

It was a pleasure to collaborate on this fascinating work, now published in AGU Advances! 📖

Happy to announce our book chapter, Cirrus Cloud Thinning (CCT), is now published! 📖☁️

We discuss the need for a better representation of cirrus cloud processes in models to validate CCT efficacy.
