Running the weather pipeline
Python
Use python3. This workspace does not provide a python shim.
After installing dependencies in the project virtual environment, prefer .venv/bin/python.
Required packages
Install:
python3 -m venv .venv
.venv/bin/pip install -r requirements.txt
The pipeline requires these runtime dependencies:
requestsnumpyxarraycfgribeccodesmercantilemapbox-vector-tile
Commands
Run the full pipeline:
.venv/bin/python src/weather_pipeline.py
Run individual steps:
.venv/bin/python src/gfs_downloader.py
.venv/bin/python src/grid_builder_v2.py
.venv/bin/python src/vector_tile_generator.py
Wave fields in the weather tiles come from the downloader and grid builder. If you want wh/wdir/wp to contain real data instead of compatibility zeros from older grid JSON, rerun the downloader before rebuilding grids and tiles.
The weather tile generator now builds z=2,4,6,8,10,12 by default so wind barb density stays usable after zooming in. If you need a custom set, override with WEATHER_TILE_ZOOMS, for example:
WEATHER_TILE_ZOOMS=2,4,6,8,10,12,14 .venv/bin/python src/vector_tile_generator.py
