Paris weather reports and daily highs since 2020

• Window: 2020-01-01 to the most recent completed day, refreshed each morning. Report times are UTC. The calendar date is on Central European Time (UTC+1) all year, no daylight saving shift, so each calendar day spans 24 hours.
• Grain: one row per report. 117,379 reports over 2,443 days from 2020-01-01 to 2026-09-08 at the first build. Routine METAR reports arrive about hourly. Special SPECI reports arrive when conditions change. A typical month holds 1,297 to 1,585 rows.
• Cadence: one new day of reports each morning. Reported daily highs and lows are final after the last report for each calendar date.
• Station: Charles de Gaulle Airport, ICAO code LFPG, the station whose reports settle daily temperature questions for Paris.

• station: the ICAO code of the reporting station, always LFPG.
• event_time_utc: the report time in UTC.
• observation_type: METAR for a routine report, SPECI for a special report.
• local_standard_date: the calendar date on Central European Time.
• temp_f, dewpoint_f: air temperature and dew point, degrees Fahrenheit. temp_c: air temperature, degrees Celsius.
• relative_humidity_pct: relative humidity, percent.
• wind_direction_degrees, wind_speed_kt, wind_gust_kt: wind direction clockwise from true north, sustained speed and gust, knots.
• altimeter_inhg, sea_level_pressure_hpa: altimeter setting in inches of mercury and sea-level pressure in hectopascals.
• sky_cover_1 to sky_cover_4, sky_base_1_ft to sky_base_4_ft: up to four sky-cover layers with each base height in feet.
• visibility_miles: horizontal visibility, statute miles.
• weather_codes: present-weather codes such as RA, SN, FG, TS.
• precipitation_in_1h: one-hour precipitation, inches.
• peak_wind_gust_kt, peak_wind_direction_degrees, peak_wind_time: peak wind from the report remarks.
• snow_depth_inches: snow depth, inches.
• raw_metar: the original report text.
• metar_high_f, metar_low_f, metar_high_c, metar_low_c: highest and lowest temperature on the row's calendar date, in Fahrenheit and Celsius, calculated from all reports for that date.
• cli_high_f, cli_low_f, cli_product, cli_report_type: always null: no National Weather Service climate report exists outside the United States. Kept so every city table shares one schema.

Absent fields are null, never zero. A trace of precipitation is null. Unreported sky layers are null. The derived daily range is null only on a day with no parsable temperature.
