Solar Radiance

This Date in Past Years

Graphed below are the minimum and maximum solar radiance on this date each year since 2008. Shown in black is the theoretical solar radiance. Places where the actual radiance dips below the theoretical are the result of cloud cover. Scant, passing clouds create sharp spikes, while persistant cloud cover will show as a more prominent dip.
