Figure 4

Visualization of the classification of weather conditions by patterns using measurement values from Lindenberg, Germany. Cloudless days feature high daily means with only little daily variability . Days with overcast sky can be characterized by low daily means and low to mid variability. Days with broken clouds feature a high daily variability and mid to high daily means. The black points refer to the example days of Figure 3.
