Exoclimes Simulation Platform
The Exoclimes Simulation Platform (ESP) was born from a necessity to move beyond Earth-centric approaches to understanding atmospheres. Our dream and vision is to provide the exoplanet community with an open-source, freely-available, ultra-fast and cutting-edge set of simulational tools for studying exoplanetary atmospheres. The ESP harnesses the power of GPUs (graphic processing units), found in most Macs nowadays, to produce speed-ups at the order-of-magnitude level. These speed-ups are invested in building intuition and studying how atmospheric dynamics, chemistry and radiation interact in various ways. Our ultimate goal is for users to become co-developers. The ESP team is committed to quality, precision and transparency at the highest level.

HELIOS-K is available for download in the "Source Code" section, which provides a link to GitHub.com. The research paper, which has been submitted to the Astrophysical Journal, is available in the "Papers" section (Grimm & Heng 2015).
We have just released our initial version of HELIOS-K, which is an ultrafast opacity calculator that takes a line list as an input and computes the line shapes of an arbitrary number of spectral lines (~millions to billions). HELIOS-K is capable of computing 100,000 spectral lines in 1 second, orders of magnitude faster than most other codes on the market. (It is hard to do a comparison, because most of these codes are proprietary and the computational times taken are not published and are obtained via private communication.) The manuscript has been submitted to the Astrophysical Journal; the submitted version is available for download in the "Papers" section of the website (Grimm & Heng 2015). The CUDA source code will be publicly available as soon as we have cleaned up some loose ends.
Test run with wave running through a modified Yin Yang grid. See Staniforth & Thuburn (2012, QJRMS, 138, 1) for a review of grids used in climate modeling.
We will develop three dynamical cores for THOR (Grimm, Grosheintz and Mendonca).
