Bundles some of the parametrizations for middle and upper atmospheric
ionization and recombination rates for precipitating
auroral and radiation-belt electrons as well as protons.
Includes also some recombination rate parametrizations to convert
the ionization rates to electron densities in the upper atmosphere.
See [References](#references) for a list of included parametrizations.
:warning: This package is in **beta** stage, that is, it works for the most part
and the interface should not change (much) in future versions.
Documentation is available at <https://pyeppaurora.readthedocs.io>.
## Install
### Requirements
- `numpy` - required
- `scipy` - required for 2-D interpolation
- `pytest` - optional, for testing
### eppaurora
An installable `pip` package called `eppaurora` is available from the
main package repository, it can be installed with:
```sh
$ pip install eppaurora
```
The latest development version can be installed
with [`pip`](https://pip.pypa.io) directly from github
(see <https://pip.pypa.io/en/stable/reference/pip_install/#vcs-support>
and <https://pip.pypa.io/en/stable/reference/pip_install/#git>):
```sh
$ pip install [-e] git+https://github.com/st-bender/pyeppaurora.git
```
The other option is to use a local clone:
```sh
$ git clone https://github.com/st-bender/pyeppaurora.git
$ cd pyeppaurora
```
and then using `pip` (optionally using `-e`, see
<https://pip.pypa.io/en/stable/reference/pip_install/#install-editable>):
```sh
$ pip install [-e] .
```
or using `setup.py`:
```sh
$ python setup.py install
```
Optionally, test the correct function of the module with
```sh
$ py.test [-v]
```
or even including the [doctests](https://docs.python.org/library/doctest.html)
in this document:
```sh
$ py.test [-v] --doctest-glob='*.md'
```
## Usage
The python module itself is named `eppaurora` and is imported as usual.
All functions should be `numpy`-compatible and work with scalars
and appropriately shaped arrays.
```python
>>> import eppaurora as aur
>>> ediss = aur.rr1987(1., 1., 8e5, 5e-10)
>>> ediss
3.3693621076457477e-10
>>> import numpy as np
>>> energies = np.logspace(-1, 2, 4)
>>> fluxes = np.ones_like(energies)
>>> # ca. 100, 150, 200 km
>>> scale_heights = np.array([6e5, 27e5, 40e5])
>>> rhos = np.array([5e-10, 1.7e-12, 2.6e-13])
>>> # energy dissipation "profiles"
>>> # broadcast to the right shape
>>> ediss_prof = aur.fang2008(
... energies[None, :], fluxes[None, :],
... scale_heights[:, None], rhos[:, None]
... )
>>> ediss_prof
array([[1.37708081e-49, 3.04153876e-09, 4.44256875e-07, 2.52699970e-08],
[1.60060833e-09, 8.63248169e-08, 3.64564419e-09, 1.62591310e-10],
[5.19369952e-08, 2.34089350e-08, 5.17379303e-10, 3.19504690e-11]])
```
Basic class and method documentation is accessible via `pydoc`:
```sh
$ pydoc eppaurora
$ pydoc eppaurora.brems
$ pydoc eppaurora.conductivity
$ pydoc eppaurora.electrons
$ pydoc eppaurora.protons
$ pydoc eppaurora.recombination
```
