Haze

Haze is often caused by aerosols such as dust, smoke, or pollution. It adds path radiance, making scenes look washed out and reducing contrast.

Haze can break vegetation indices and classification models if not handled. Some atmospheric correction methods estimate aerosol properties, but haze remains challenging under variable conditions.

A practical approach is to use quality layers, prefer surface reflectance products, and avoid interpreting small changes during hazy periods. For time series, consistency and robust filtering usually matter more than one perfect correction.
