Plot Description:

This plot attempts to show the impact of cloudiness on temperatures. The plot shows a simple difference between the average temperature during cloudy/mostly cloudy conditions and the average temperature by hour and by week of the year. The input data for this chart is limited to post 1973 as cloud cover data since then is more reliable/comparable.
