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.

The iridescence is due to light scattering by very small cloud particles (< 10 µm) ❄️
A large number of very small ice particles is characteristic of homogeneous ice nucleation, occurring in the absence of aerosols.

Interesting observation! It seems that 🛰️ Aqua/MODIS cloud fraction retrieval detects 🌋 plume as cloud, whereas cloud effective radius retrieval is more accurate. #Satellite imagery via #NASA #Worldview (8 Feb) #Reykjanes #Grindavik #Iceland #volcano #Eruption #cloud #aerosol
