I currently read a few papers and one of them stated to forecast solar irradiance using measures of solar radiation.
I hope this question is not trivial as I'm actually from germany, but if there is a specific difference between these two terms I would be glad if someone could explain it.

Solar irradiation is a measure of the energy delivered by the sun per unit area, watts or joules per square metre for example.. It is often recorded over a specific time period, so it is very much to do with solar radiation, but not exactly the same thing.

  • $\begingroup$ that already explains a lot, but is irradiation and irradiance also the same? regarding [quora.com/… it seems that irradiation is not very much used. So what would you say is the actual difference between solar irradiance and solar radiation? in your answer you only refer to irradiation, it would be really nice if you could compare the terms if that's possible $\endgroup$ – Marcel H.

  • $\begingroup$ Solar radiation is the radiation emitted by the sun and without which there would be no advanced life on Earth. Nearly all living things depend on it. $\endgroup$ – Michael Walsby Jul 21 at 13:02
  • $\begingroup$ okay, that helped a lot! thank you very much, so I guess solar radiation is just a term describing the radiation coming from the sun, whereas solar irradiation is a scientific term describing a power per unit area ratio $\endgroup$ – Marcel H. Jul 21 at 13:08
  • $\begingroup$ That's right, you've got it! $\endgroup$ – Michael Walsby Jul 21 at 13:56
