Conditional Local Convolution for Spatio-Temporal Meteorological Forecasting

This is a Official PyTorch implementation of CLCRN in the following paper:

Basic Requirements

• torch>=1.7.0
• torch-geometric-temporal (installation see Github: torch_geometric_temporal)

Dependency can be installed using the following command:

conda env create --file env_clcrn.yaml
conda activate CLCRN_env

Data Preparation

1） Using the preprocessed dataset:

The four datasets after preprocessed are available at Google Drive.

Download the dataset and copy it into data/ dir. And Unzip them, and obtain data/{cloud_cover,component_of_wind,humidity,temperature}/

2） Generating dataset from scratch:

The raw datasets WeatherBench(Arxiv) can be downloaded from Github: WeatherBench. And the provided scripts/generate_training_data.py is used for data preprocessing.

Dump them into dataset_release/ files, and run the following commands to generate train/test/val dataset.

# Dataset preprocess
python scripts/generate_training_data.py  --input_seq_len=12 --output_horizon_len=12

Training the Model

The configuration is set in /experiments/config_clcrn.yaml file for training process. There are two config files for clcrn/clcstn training. Run the following commands to train the target model.

# CLCRN
python train_clcrn.py --config_filename=./experiments/config_clcrn.yaml

# CLCSTN
python train_clcstn.py --config_filename=./experiments/config_clcstn.yaml
