Abstract
A method of adjusting lighting to reduce sky glow. The method includes the steps of detecting, by a plurality of sensors, an amount of cloud coverage in a region of the troposphere; determining, by a sky glow reduction circuitry, whether the amount of clouds is greater than, less than, or equal to a predetermined cloud coverage threshold; and adjusting, by a light output controller circuitry, a light output of a plurality of light sources to reduce sky glow if the amount of clouds is less than or equal to the predetermined cloud coverage threshold. The adjusting step is at least partially based on a predetermined policy.
