Earth's solar constant
WebFeb 5, 2024 · Note that this value is indeed that on the top of the atmosphere. The average value on Earth should take into account the absorption through the atmosphere, reducing the intensity to roughly $1000$ W/m$^2$. This value of course depends on your latitude on Earth - the closer to the pole, the thicker the atmosphere layer. We talk about "air mass".
