PhotochemPy is a photochemical model of rocky planet's atmospheres. Given inputs, like the stellar UV flux, the atmospheric temperature structure, etc., this code will find the steady-state chemical composition of an atmosphere, or evolve atmospheres through time.
PhotochemPy is a Python wrapper to Fortran source code. This makes the code very speedy, but also user-friendly.
Requirements: To install PhotochemPy, you must have the following installed on your system.
Python
(>3.6.0) with thenumpy
package. I suggest using anaconda to install these regardless of your operating system.- The GNU compiler collection, version >4.9.4 (includes
gfortran
,gcc
, etc.). If you are using a Mac, I suggest installing it with Homebrew:brew install gcc
. For other operating systems follow this GNU installation guide. - CMake. On Mac you can install with
brew install cmake
.
Python Module: After satisfying the requirements, then follow these setups to install PhotochemPy
- Clone or download the github repository
https://github.com/Nicholaswogan/PhotochemPy
- In a terminal, navigate to the folder
src/dependencies
, and run the shell scriptcompile.sh
. - Navigate to the root directory of PhotochemPy, then install with
python -m pip install .
Fortran source: If you prefer to use the code exclusively in Fortran, that is OK too. An example is provided in the folder examples/fortran_example
.

PhotochemPy is a distant fork of the Atmos photochemical model, originally developed by Jim Kasting and Kevin Zahnle and further developed by many of their students and colleges.
