Field notes
The source is AEMET’s daily climatological observations served through AEMET OpenData; the site says it calculates averages and trends from those records and offers CSV downloads. For the smoothed view, each year combines the selected date with the seven days on either side, requiring at least 10 observations; a separate mode shows the exact day. The station profile is said to identify its first recorded year and data gaps, which matters because coverage varies by station.
