Central Source Registry

Sources used across NightBreath

This page consolidates every scientific reference and live data feed used across the platform, and shows exactly where each source appears.

Live

Actively powering current features.

Reference

Scientific or methodology grounding.

Planned

Roadmap source not yet fully integrated.

Evidence Governance

How NightBreath treats data responsibility

This is not a black-box score feed. NightBreath frames evidence as decision support, requiring transparent uncertainty communication and equity review before policy or operational action.

Transparency

Every operational recommendation should surface source freshness, missing fields, and confidence caveats.

Two-Eyed validation

Data interpretation is expected to be reviewed with place-based community knowledge before high-impact decisions.

Equity checks

Deployment decisions should be audited for who benefits first, who bears cost, and who remains excluded.

Systems trade-offs

Cooling actions are reviewed alongside housing pressure, energy demand, and biodiversity implications.

Scientific Evidence

Peer-reviewed and institutional evidence used to frame risk, mortality timing, and heat-justice rationale.

Scientific Note

Satellite LST is not identical to near-surface air temperature, but it is an essential spatial proxy for nighttime heat retention and canopy inequity. NightBreath pairs LST context with air-temperature histories from NASA POWER and Open-Meteo.
