Detailed Description

One hour of a day's weather (weather::hours, when the request asks for them).

The hours are those of the place's mean solar day: hour 0 starts at local mean midnight, 4 * longitude minutes before 00:00 UTC (east is earlier), so the day's lowest temperature comes near sunrise and the highest in the afternoon wherever the place is. In metric units the precipitation and snowfall of the 24 hours add up to the day's exactly. Values are rounded like the day's.
