README
Snow Microwave Radiative Transfer model
=============================================
[SMRT](https://www.smrt-model.science/) is a radiative transfer model to compute emission and backscatter from snowpack.
Getting started is easy, follow the [instructions](https://www.smrt-model.science/getstarted.html) and explore the other repositories
with examples in the ['smrt-model' github organization](https://github.com/smrt-model) or read the detailed ['documentation'](https://smrt.readthedocs.io/en/master/).
If you want to try without installing anything on your computer, use free mybinder.org notenooks: [](https://mybinder.org/v2/gh/smrt-model/smrt/master?filepath=examples/iba_onelayer.ipynb).
If you want to try SMRT without coding, use [SMRT-App](https://snow.univ-grenoble-alpes.fr/smrt-app/).
You can also explore the documentation and find code examples via the [AI Wiki](https://deepwiki.com/smrt-model/smrt). Please let us know your experience of using this via [discussions](https://github.com/smrt-model/smrt/discussions).
Quick Installation
--------------------
To install the latest stable release:
```console
pip install smrt
```
Alternatively, the latest developments are available using:
```console
pip install git+https://github.com/smrt-model/smrt.git
```
or by ['manual installation'](https://smrt-model.science/getstarted.html).
A simple example
--------------------
An example to calculate the brightness temperature from a one-layer snowpack.
```python
from smrt import make_snowpack, sensor_list, make_model
# create a snowpack
snowpack = make_snowpack(thickness=[10.], # snowpack depth in m
microstructure_model="sticky_hard_spheres",
density=320.0, # density in kg/m3
temperature=260, # temperature in Kelvin
radius=100e-6) # scatterers raidus in m
# create the sensor (AMSRE, channel 37 GHz vertical polarization)
radiometer = sensor_list.amsre('37V')
# create the model including the scattering model (IBA) and the radiative transfer solver (DORT)
m = make_model("iba", "dort")
# run the model
result = m.run(radiometer, snowpack)
print(result.TbV())
```
