SCIENTIFIC PROGRAM
Research tracks
Every track is designed around explicit data identity, baselines, uncertainty, validation and reproducibility.
Compound hazards
Transparent multi-hazard formulations with exposed assumptions and sensitivity analysis.
Research questions →Climate extremes
Trends, anomalies, heatwaves, hot nights and cooling-degree metrics.
Climate analysis →Air quality and smoke
Concentration-first summaries, explicit AQI standards and cautious wildfire context.
PM2.5 workflows →Urban climate
Land-surface temperature, regional workflows and geospatial validation.
Urban-heat workflow →Reproducibility
Experiment manifests, checksums, model cards, data cards and versioned artifacts.
Methods →Reproducible experiments
Run one immutable specification to produce complete metrics, uncertainty figures, paper-ready reports, checksums and a self-contained candidate release.
Open experiment orchestrator →ACCESSIBLE BY DESIGN
Three capability tiers
Standard
Deterministic core, local files, synthetic data, CPU baselines and browser tools. No paid AI API.
Local AI
Optional local language models explain existing outputs without changing decisions or measurements.
BYOK
Optional provider-neutral cloud models and credentialed data connectors using user-managed secrets.
OPEN DEMONSTRATIONS
Browser tools
Public tools translate the scientific core into inspectable decisions and local-first workflows.
Ventilation Decision
Balance heat removal with PM2.5, smoke, humidity, wind and airflow.
Open tool →Home Heat Profile
Identify likely heat pathways without producing a certified score.
Open tool →Cooling Cost
Expose energy, price and duty-cycle assumptions.
Open tool →Indoor–Outdoor Comparator
Inspect thermal lag and observational response without causal overclaiming.
Open tool →Built to be cited, inspected and extended.
The repository includes typed APIs, CLI workflows, Docker, CI, CodeQL, tests, provenance contracts, citation metadata and a research roadmap.
