Why these scores
Citation Discipline
Multi-stage review across thousands of expert + government reviewers; methodology + uncertainty explicit.
Methodology + data quality documented per dataset; peer-reviewed climate research.
Modern Reference
Open-access reports + interactive atlas; structured data; DOI per major report.
NOAA APIs + bulk-data + open license; broad LLM corpus + scientific community usage.
Citation Velocity
Default global citation for climate science; cited by every major climate assessment + policy body.
Cited daily by news (weather + climate) + AI engines; default for atmospheric data claims.
