Snow Microwave Radiative Transfert model to compute thermal emission and backscatter from snowpack
SMRT is a radiative transfer model to compute emission and backscatter from snowpack.
Getting started is easy, follow the instructions and explore the other repositories
with examples in the ‘smrt-model’ github organization or read the detailed ‘documentation’.
If you want to try without installing anything on your computer, use free mybinder.org notenooks: 
.
If you want to try SMRT without coding, use SMRT-App.
To install the latest stable release:
pip install smrt
Alternatively, the latest developments are available using:
pip install git+https://github.com/smrt-model/smrt.git
or by ‘manual installation’.
An example to calculate the brightness temperature from a one-layer snowpack.
