THOR uses an icosahedral grid. Starting from a icosahedron each of the 20 triangles is refined and projected onto the sphere. The result is a nearly uniform grid with no clustering of cells near the poles.
The manuscript of Heng, Lyons & Tsai (2015), which deals with a formalism for understanding atmospheric chemistry from the viewpoint of an astrophysicist, has just been accepted by the Astrophysical Journal.
The Exoclimes Simulation Platform (ESP) was born from a necessity to move beyond Earth-centric climate simulators, to provide the scientific community studying exoplanets with an ultra-fast, open-source and all-encompassing set of simulational tools. The ESP is designed to harness the power of GPU (graphics processing unit) computing, which affords a speed-up at the order-of-magnitude level. Our ultimate goal is for ESP users to become co-developers.
