# Localized Weather

This repository contains the code and data for the paper ["Local Off-Grid Weather Forecasting with Multi-Modal Earth Observation Data"](https://arxiv.org/abs/2410.12938).

The paper presents a novel multi-modal method that downscales gridded weather forecasts, such as ERA5 and HRRR, to provide accurate off-grid predictions. The model leverages both global data and local weather station observations from MADIS to make predictions that reflect both large-scale atmospheric dynamics and local weather patterns.

The model is evaluated on a surface wind prediction task and shows significant improvement over baseline methods, including ERA5 and HRRR interpolation and a multi-layer perceptron.

# Model and data
## Data

The data for training, testing and validation can be found on [Zenodo](https://zenodo.org/records/15346612).

The following data is available:
- Shapefile of the Northeastern United States (NE-US, extracted from [NWS](https://www.weather.gov/gis/USStates))
- Shapefile containing the location and number of observations (2019-2023) of the MADIS stations in NE-US
- Processed hourly averaged [MADIS](https://madis.ncep.noaa.gov/) data for the NE-US (2019-2023)
- [ERA5](https://confluence.ecmwf.int/display/CKB/ERA5%3A+data+documentation) re-analysis data for the NE-US (2019-2023), gridded and interpolated
- [HRRR](https://rapidrefresh.noaa.gov/hrrr/) analysis and forecast data for the NE-US (2019-2023), gridded and interpolated

For MADIS, ERA5 and HRRR, the following variables are available:
- u and v component of wind vector at 10 meters above ground
- temperature at 2 meters above ground
- dewpoint at 2 meters above ground

The data can also be generated from scratch.
For this, code is available under `Source/DataDownload/{ERA5/MADIS/HRRR}` for the raw data download, and in the respective data loaders for the data processing (`Source/Dataloader/{ERA5/HRRR/MetaStation/Madis/MixDataMLP}.py`).

## Code
The code is organised as follows (in `Source/`):
- `LocalLauncher.py`, and `SLURM_job_launcher.py` are two different launchers all eventually pointing at `Main.py` (the arguments from the slurm job launcher are parsed by `Arg_Parser.py`)
- `Main.py` contains the main code loop
- `EvaluateModel` contains the code for the evaluation of the model, as well as the back propagation
- the folder `Dataloader/` contains the data loaders for MADIS, HRRR and ERA5, and the combination of them, and the folder `Network/` the code for the network construction, for both the internal (MADIS) and external (ERA5 to MADIS) connections
- `Modules/GNN/MPNN.py` contains the code for the heterogeneous message passing neural network and calls `GNN_Layer_Internal/External.py`, the message passing sequences between the networks
- `Modules/Transformer/ViT.py` contains the code for the transformer and calls `Transformer/StationsEmbedding.py`.

### Code inputs
The code expects the following data structure, you need to specify the root data path in the launcher:
