Where this comes from

Not loaded

Values marked modelled are estimates from a regional model, not a measurement at your location. Breathe never blurs that distinction.

Privacy

Run the reference node locally and Breathe will read real measurements from /bxp/v2/nearby alongside the modelled feed. Leave blank to use the modelled source only.
