## About
Atmodeller is a Python package that uses [JAX](https://jax.readthedocs.io/en/latest/index.html) to compute the partitioning of volatiles between a planetary atmosphere and its rocky interior. It is released under [The GNU General Public License v3.0 or later](https://www.gnu.org/licenses/gpl-3.0.en.html).

## Documentation

The documentation is available online, with options to download it in EPUB or PDF format:

[https://atmodeller.readthedocs.io/en/latest/](https://atmodeller.readthedocs.io/en/latest/)

## Quick install

Atmodeller is a Python package that can be installed on a variety of platforms (e.g. Mac, Windows, Linux). It is recommended to install Atmodeller in a dedicated Python environment. Before installation, create and activate the environment, then run:

```pip install atmodeller```

Downloading the source code is also recommended if you'd like access to the example notebooks in `notebooks/`.

## Basic usage

Jupyter notebooks in the `notebooks/` directory demonstrate how to perform single and batch calculations, and how to integrate Atmodeller into time-dependent simulations. A simple example of how to use Atmodeller is provided below:

```
from atmodeller import (
    InteriorAtmosphere,
    Planet,
    Species,
    SpeciesCollection,
    earth_oceans_to_hydrogen_mass,
)
from atmodeller.solubility import get_solubility_models

solubility_models = get_solubility_models()
# Get the available solubility models
print("solubility models = ", solubility_models.keys())

H2_g = Species.create_gas("H2")
H2O_g = Species.create_gas("H2O", solubility=solubility_models["H2O_peridotite_sossi23"])
O2_g = Species.create_gas("O2")

species = SpeciesCollection((H2_g, H2O_g, O2_g))
planet = Planet()
interior_atmosphere = InteriorAtmosphere(species)

oceans = 1
h_kg = earth_oceans_to_hydrogen_mass(oceans)
o_kg = 6.25774e20
mass_constraints = {
    "H": h_kg,
    "O": o_kg,
}

# If you do not specify an initial solution guess then a default will be used
# Initial solution guess number density (molecules/m^3)
initial_log_number_density = 50

interior_atmosphere.solve(
    planet=planet,
    initial_log_number_density=initial_log_number_density,
    mass_constraints=mass_constraints,
)
output = interior_atmosphere.output

# Quick look at the solution
solution = output.quick_look()

# Get complete solution as a dictionary
solution_asdict = output.asdict()
print("solution_asdict =", solution_asdict)

# Write the complete solution to Excel
output.to_excel("example_single")
```

## Funding
Atmodeller was created as part of a SERI-funded ERC Starting grant '2ATMO' granted to P. Sossi (Contract no. MB22.00033), with additional funding provided through a Swiss National Science Foundation (SNSF) Eccellenza Professorship (#203668).
