Software to work with the TorNet dataset as described in the paper A Benchmark Dataset for Tornado Detection and Prediction using Full-Resolution Polarimetric Weather Radar Data
The TorNet dataset can be downloaded from the following location:
TorNet is split across 10 files, each containing 1 year of data. There is also a catalog CSV file that is used by some functions in this repository.
- Tornet 2013 (3 GB) and catalog: https://zenodo.org/doi/10.5281/zenodo.10558658
- Tornet 2014 (15 GB): https://zenodo.org/doi/10.5281/zenodo.10558838
- Tornet 2015 (17 GB): https://zenodo.org/doi/10.5281/zenodo.10558853
- Tornet 2016 (16 GB): https://zenodo.org/doi/10.5281/zenodo.10565458
- Tornet 2017 (15 GB): https://zenodo.org/doi/10.5281/zenodo.10565489
- Tornet 2018 (12 GB): https://zenodo.org/doi/10.5281/zenodo.10565514
- Tornet 2019 (18 GB): https://zenodo.org/doi/10.5281/zenodo.10565535
- Tornet 2020 (17 GB): https://zenodo.org/doi/10.5281/zenodo.10565581
- Tornet 2021 (18 GB): https://zenodo.org/doi/10.5281/zenodo.10565670
- Tornet 2022 (19 GB): https://zenodo.org/doi/10.5281/zenodo.10565691
If downloading through your browser is slow, we recommend downloading these using zenodo_get (https://gitlab.com/dvolgyes/zenodo_get).
After downloading, there should be 11 files, catalog.csv, and 10 files named as tornet_YYYY.tar.gz. Move and untar these into a target directory, which will be referenced using the TORNET_ROOT environment variable in the code. After untarring the 10 files, this directory should contain catalog.csv along with sub-directories train/ and test/ filled with .nc files for each year in the dataset.
Basic python requirements are listed in requirements/basic.txt and can be installed using pip install -r requirements.txt.
The tornet package can then installed into your environment by running
pip install .
in this repo. To do ML with TorNet, additional installs may be necessary depending on library of choice. See e.g., requirements/tensorflow.txt, requirements/torch.txt.
Start with notebooks/DataLoaders.ipynb to get an overview on loading and visualizing the dataset.
The following trains the CNN baseline model described in the paper using tensorflow. If you run this out-of-the-box, it will run very slowly because it uses the basic dataloader. Read the DataLoader notebook for tips on how to optimize the data loader.
# Set path to dataset
export TORNET_ROOT=/path/to/tornet
# Run training
python scripts/tornado_detection/train_tornado_tf.py scripts/tornado_detection/config/params.json
Weights of a pretrained CNN baseline are provided in model/. To evaluate this model on the test set, run
# Set path to dataset
export TORNET_ROOT=/path/to/tornet
# Evaluate trained model
python scripts/tornado_detection/test_tornado_tf.py models/tornado_detector_baseline.SavedModel
This will compute and print various metrics computed on the test set.
