Plot Description:

Based on available hourly observation reports by METAR stations, this application presents the top 10 events for a given metric of your choice. Please note that this application often reveals bad data stored within the database. Please do contact us when you see suspicious reports and we'll clean up the database.

You can optionally generate this plot for an explicit period of days, the year is ignored with only the month and day portion used. If you set the start date to a date later than the end date, then the effect is to consider the date period crossing 1 January.

If you pick the same start and end date, you effectively get the extremes for that date.

The CSV/Excel download option for this autoplot will return 100 unfiltered events for further usage as you see fit.
