Not really, because real sunlight at the surface of the planet is a variable. It literally varies from minute to minute, day to day, and season to season. It's different from cloudy to clear, all that. And interestingly enough, it's different from low elevation to high elevation, which makes shooting color in the mountains... challenging?
That said, "daylight" is fairly well understood. The graphics arts communities have studied the heck out of it, because they have to. Can't do their work without understanding how it's going to be viewed. And from this understanding has come some standards.
Look up the
D50 standard (GTI can explain it way better than I can). Might be what you're looking for. IDK. But it's a place to start.
Oh, and a great proponent of "north light" was Frank Lloyd Wright. You might want to tour Taliesin if you can. The main studio is covered by north facing skylights. Has to be experienced. Really easy on the eyes; I could feel myself relaxing as I walked into the room. Very nice.
Another is De Beers (the diamond people). They grade the color of their diamonds by north light, or they used to. Guy I met who worked there for a while said they could only grade diamonds a few hour a day in the winter at that latitude. I imagine they've "fixed" this by now, but IDK.
