My upcoming project (over the summer) is about studying the atmospheric dynamics of the Precambrian Earth using 3D atmospheric science models (probably using the CAM3 models often used for modelling the Earth's atmosphere). I am then planning to move onto a project to model the 3D dynamics of Earth's atmosphere around various types of stars, which should hopefully help us predict what the atmosphere of an Earth-like exoplanet should look like (spectrally) around various star types
So basically, my primary interests are astronomy and atmospheric science (I'm also really into computer science and statistics, which should help with both). I could say that astrobiology merges them all, but I'm unsure if anything astrobiologically significant will ever come out.
I'm also into super-long-term sustainability, which makes this very relevant (most of the shorter-term sustainability things are already clogged up with people)
What kind of models are used for modelling the atmosphere? Do you use lots of finite-element methods?
There must be quite a few undergrad/graduate/post-doc/???-level researchers on LessWrong. I'm interested in hearing about your work. I'll post about myself in the comments.
