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/latest/).

If you want to try without installing anything on your computer, use free mybinder.org notenooks: [![Binder](https://mybinder.org/badge.svg)](https://mybinder.org/v2/gh/smrt-model/smrt/master?filepath=examples/iba_onelayer.ipynb)

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())

```
