Canadian Climate Anomaly Intelligence
Monthly temperature and precipitation anomalies versus 1981-2010 climate normals for a curated panel of long-record Canadian climate stations, from ECCC's keyless MSC GeoMet OGC API (climate-monthly collection). Each row is one (station, month): mean/min/max temperature, the official normal, the temperature anomaly in C, total precipitation, its normal, the precipitation anomaly in %, snowfall, heating/cooling degree days, warm/cold/wet/dry extreme-month flags, station-record warmest/coldest flags, and a documented 0-100 extreme_score (0.50 |temp anomaly| + 0.30 |precip anomaly| + 0.20 station-record flag) ranked per month with a top-10 most-extreme flag. Station-months below the 25-valid-day coverage gate are dropped, never interpolated. Units: degrees C; mm; %. Caveats: station-identifier based (retired identifiers end, never spliced); ECCC revises history so re-ingests can legitimately differ; normals reference 1981-2010.
