Atmospheric moisture tracking model

Atmospheric moisture tracking

This repository contains the source code of the WAM2layers moisture tracking code originally developed by Ruud van der Ent. It can be used to determine where precipitation originally evaporated (backtracking), or where evaporated moisture eventually ends up (forward tracking).

See the documentation for a more detailed description.

How to use

# Advised but not strictly needed
conda create -n wam2layers -c conda-forge python=3.9 jupyterlab cartopy matplotlib
conda activate wam2layers

# Simple user installation
pip install [e-mail]:WAM2layers/WAM2layers.git


# Editable (develop) installation
git clone [e-mail]:WAM2layers/WAM2layers.git
cd WAM2layers/
pip install -e .[develop]

# Download sample data and update paths in config file
https://rebrand.ly/wam2layers-example-data

# Run the example backtrack script
wam2layers backtrack floodCase_202107.yaml
wam2layers visualize output floodCase_202107.yaml

Other versions

This is the official codebase for the WAM-2layers moisture tracking model as of 18/03/2022, but there are still several other versions around:

• Original Python code by Ruud van der Ent
• Adapted version by Imme Benedict

Reuse and acknowledgement

To be completed.

We are actively developing the code at the moment, so it may be subject to change. We encourage anyone who is interested in re-using the code to get in touch. We may be able to help.

If you use the code for a publication, please cite it using the DOI of the appropriate release and/or the following paper: Contrasting roles of interception and transpiration in the hydrological cycle - Part 2: Moisture recycling
