Colour as a signal for entraining the mammalian circadian clock.

PLoS Biology, 2015
Twilight is characterised by changes in both quantity ("irradiance") and quality ("colour") of light. Animals use the variation in irradiance to adjust their internal circadian clocks, aligning their behaviour and physiology with the solar cycle. However,

Solar irradiance measurements

Living Reviews in Solar Physics
The Sun provides nearly all the energy powering the Earth’s climate system, far exceeding all other energy sources combined. The incident radiant energy, the “total solar irradiance,” has been measured by an uninterrupted series of temporally overlapping

Effects of total solar eclipse of 29 March 2006 on surface radiation [PDF]

Atmospheric Chemistry and Physics, 2007
Solar irradiance spectral measurements were performed during a total solar eclipse. The spectral effect of the limb darkening to the global, direct irradiance and actinic flux measurements was investigated.
