Exoclimes Simulation Platform (ESP)

ESP Computer Codes

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.

ESP Summer School

The next, exciting phase for us in this open-source movement is to teach the community how to use these codes, so that they may become both users and co-developers.  Held every June, the ESP summer school is aimed at students and postdocs who are interested in exoplanet science. Participants of the ESP summer school are competitively selected; participation is capped at 30 persons.


To apply, please send a one-page letter (use a maximum of 2 pages if you must) with the following information:

  1. Introduce yourself, stating your past and current universities/institutions, area(s) of study and Ph.D/postdoc advisor(s).
  2. Describe your current and/or future ideas for your thesis work and explain how the ESP will help you in your work.
  3. List the names, affiliations and email addresses of two professors or senior researchers who will be able to serve as references for you. We may solicit feedback from these individuals if necessary.

We will vet and select participants based on achieving topical, geographic and gender diversity, as well as a balance between the experience levels of the participants. The letter should be in PDF format and sent directly to the CSH Director (E-Mail) by 31st December of each year. For more details, please read the relevant documents.
