Open-Meteo free tier is NON-COMMERCIAL ONLY; subscriptions and advertising are named as commercial use in the published terms. This binds both weather and aerosol at once, so Syzygy cannot carry advertising or a subscription while it uses them.

CC-BY-4.0 sources require attribution of both Open-Meteo and the underlying model.

Photographs and reconstructed conditions are the work of one photographer. Exact locations are deliberately not published; places appear as named areas. Every atmospheric value is model output, never a measurement taken at the site.
