The Exoclimes Simulation Platform (ESP) is a vision to provide the scientific community with publicly-available computer codes designed to simulate the climates of exoplanets, including radiative transfer, chemistry and fluid dynamics. It is based on the belief that a healthy exoplanetary atmospheres community should compete to publish the best ideas, rather than be constrained by proprietary software. It is also based on the belief that science should be reproducible and accessible to everyone who is interested. The ESP family of codes include THOR (a non-hydrostatic general circulation model), HELIOS (an improved two-stream radiative transfer code), VULCAN (a chemical kinetics code), HELIOS-K (an opacity calculator), HELIOS-R2 (an atmospheric retrieval code), HELA (a machine-learning retrieval code), LX-MIE (a Mie scattering code), etc.
