Plot Description:

This plot presents hourly variable metrics from automated stations. Values are partitioned by week of the year to smooth out some of the day to day variation.

Updated 28 Jun 2022: Partitioning by week is now done by taking the day of the year divided by 7 instead of iso-week calculation. This hopefully makes the data presentation more straight forward.
