Hardware

Sensing components are distributed under CERN-OHL. AirCal assumes zero liability for custom modifications or unauthorized assembly variants.

Software & Data

The aggregate public stream is provided via CC BY 4.0. You are permitted to integrate this data commercially, provided attribution is structurally visible.

Malicious injection into the AirCal grid is heavily restricted. Submissions must be raw, unmanipulated laser-scattering outputs originating from verified node identities.

• NO API SCRAPING BEYOND RATE LIMITS.
• NO DATA SPOOFING OR PAYLOAD ALTERATION.
• NO REVERSE ENGINEERING OF ALGORITHMIC COMPENSATION ARTIFACTS.

Data is statistical. Sensor drift occurs. The network is not a substitute for critical health or government emergency warning systems. Liability for exposure decisions rests entirely on the subject.
