Researchers can measure the intensity of sunlight using a,, or. To calculate the amount of sunlight reaching the ground, both the of Earth's and the by have to be taken into account. The extraterrestrial solar illuminance (Eext), corrected for the elliptic orbit by using the day number of the year (dn), is given to a good approximation by.
