US city daily weather panel, 20 metros
Daily observed weather for 20 US metro airport stations (New York, Los Angeles, Chicago, Houston, Phoenix, Seattle, Miami, Boston, Atlanta, Dallas, San Francisco, Washington, Denver, Minneapolis, Detroit, Philadelphia, St. Louis, Nashville, Portland, Las Vegas) from NOAA GHCN-Daily (keyless .dly files, public domain). Trailing 370 days, updated daily: max/min temperature (degC), precipitation (mm), snowfall and snow depth (cm), heating/cooling degree days (base 18 degC, computed from the daily mean) plus ML-ready flags — heatwave (tmax>=32), deep freeze (tmin<=-15), heavy precipitation (>=25mm). GHCN -9999 (missing) becomes NULL, never imputed.

| Colonne | Type | Description |
|---|---|---|
| date | date | Date of observation (station local date). (unit: date) |
| city | string | Metro city label (curated station city). |
| region | string | Province/territory (CA) or state (US) code. |
| country | string | Country name (Canada or United States). |
| country_code | string | ISO 3166-1 alpha-3 country code (CAN or USA). |
| lat | float | Station latitude, decimal degrees. (unit: degrees) |
| lon | float | Station longitude, decimal degrees. (unit: degrees) |
| station_id | string | Upstream station identifier: ECCC CLIMATE_IDENTIFIER (CA) or GHCN-Daily station ID (US). |
| station_name | string | Upstream station name, verbatim. |
| temp_max_c | float | Daily maximum temperature, degrees Celsius. (unit: °C) |
| temp_min_c | float | Daily minimum temperature, degrees Celsius. (unit: °C) |
| temp_mean_c | float | Derived: daily mean temperature = (temp_max_c + temp_min_c) / 2, degrees Celsius. NULL when either bound is missing. (unit: °C) |
| precip_mm | float | Total daily precipitation, millimetres. (unit: mm) |
| snowfall_cm | float | Total daily snowfall, centimetres. (unit: cm) |
| snow_on_ground_cm | float | Snow depth on the ground, centimetres. (unit: cm) |
| hdd_18 | float | Heating degree days, base 18 degC. ECCC-published for the Canadian panel; computed from temp_mean_c for the US panel (max(0, 18 - mean)). (unit: degree days) |
| cdd_18 | float | Cooling degree days, base 18 degC. ECCC-published for the Canadian panel; computed from temp_mean_c for the US panel (max(0, mean - 18)). (unit: degree days) |
| heatwave_flag | boolean | Derived: temp_max_c >= 32.0 degC. Connector-defined transformation. |
| deep_freeze_flag | boolean | Derived: temp_min_c <= -15.0 degC. Connector-defined transformation. |
| heavy_precip_flag | boolean | Derived: precip_mm >= 25.0 mm. Connector-defined transformation. |
| data_source | string | Upstream source label for the row. |
