As received, this weather data doesn’t describe the columns. I fed the list of column names into ChatGPT and asked it for some descriptions, in case it was a known data format.


This dataset appears to be a collection of weather observations, possibly from METAR (Meteorological Aerodrome Report) data, which is commonly used in aviation and meteorology. Here’s a breakdown of what each column likely represents:

  1. id1/id2: These columns could be indexing columns that might have been created during the data export or import process. They typically do not hold meaningful information and can be dropped.

  2. station: The station identifier (e.g., “JYO”) where the weather observation was recorded. “JYO” refers to Leesburg Executive Airport in Virginia, USA.

  3. valid: The timestamp of the observation, given in UTC (Coordinated Universal Time).

  4. tmpf: Temperature in Fahrenheit.

  5. dwpf: Dew point temperature in Fahrenheit.

  6. relh: Relative humidity as a percentage.

  7. drct: Wind direction in degrees from true north.

  8. sknt: Wind speed in knots.

  9. p01i: Precipitation in inches in the past hour.

  10. alti: Altimeter setting in inches of mercury, which is used to measure atmospheric pressure.

  11. mslp: Mean sea-level pressure in millibars (if provided). This is often NaN if not reported.

  12. vsby: Visibility in miles.

  13. gust: Wind gusts in knots, if reported. This is often NaN if no gusts were observed.

  14. skyc1: Sky condition at the first cloud layer (e.g., “CLR” means clear).

  15. skyc2 / skyc3 / skyc4: Sky condition at subsequent cloud layers, if present. These are NaN if there are no additional layers.

  16. skyl1 / skyl2 / skyl3 / skyl4: Heights of the cloud layers in feet above ground level, corresponding to skyc1, skyc2, etc. These are NaN if no clouds are observed.

  17. wxcodes: Weather phenomena codes (e.g., “RA” for rain, “SN” for snow). NaN if none are reported.

  18. ice_accretion_1hr / 3hr / 6hr: Ice accretion in inches over the past 1, 3, or 6 hours. Often NaN unless icing conditions are present.

  19. peak_wind_gust: The peak wind gust observed during the reporting period, in knots.

  20. peak_wind_drct: The direction of the peak wind gust, in degrees from true north.

  21. peak_wind_time: The time at which the peak wind gust occurred.

  22. feel: Apparent temperature or “feels like” temperature in Fahrenheit.

  23. metar: The raw METAR string representing the full weather observation report.

  24. snowdepth: Snow depth in inches, often NaN if no snow is present.

  25. valid_ET: The timestamp of the observation in local Eastern Time (ET).

  26. Day Of Week ET: The day of the week, possibly encoded as an integer where 0 = Monday, 1 = Tuesday, etc.

  27. sunrise / sunset: Timestamps for sunrise and sunset at the observation location, in UTC.

  28. daylight: A boolean indicating whether the observation was made during daylight hours (True) or not (False).

This should give you a good understanding of what each column represents!
