What is the irradiance of the sun dependent on?(1 point)
The irradiance of the sun is dependent on several factors including the distance between the sun and the Earth, the angle at which the sunlight hits the Earth's surface, the amount of atmosphere the sunlight has to travel through, and the presence of any clouds or pollutants in the atmosphere.
