CloudnetPy

CloudnetPy is Python software designed for producing vertical profiles of cloud properties from ground-based remote sensing measurements. The Cloudnet processing combines data from cloud radar, optical lidar, microwave radiometer, and numerical weather prediction models. Measurements and model data are brought into a common grid and classified as ice, liquid, aerosol, insects, and so on. Subsequently, geophysical products such as ice water content can be retrieved in further processing steps. See Illingworth et al. (2007) for more details about the concept.

CloudnetPy is a rewritten version of the original Cloudnet Matlab code. It features several revised methods, extensive documentation, and more.

Development

Follow the installation instructions from the source above but install with the development dependencies and pre-commit hooks:

python3 -m pip install -e .[dev,test]
pre-commit install

Run unit tests:

python3 -m pytest --flake-finder --flake-runs=2

Run single unit test:

python3 -m pytest tests/unit/test_hatpro.py

Run end-to-end tests:

python3 tests/e2e_test.py

for f in cloudnetpy/model_evaluation/tests/e2e/*/main.py; do $f; done

Force pre-commit checks (ruff, mypy, etc.) for all files:

pre-commit run --all
