You are addressing a theory I have though, not established science. Even if the sun get's 24 hours of sun, you can see from many photos of this event the sun is extremely low in the sky. Just from having kids at the pool I can tell you the difference in UV amounts between even noon and 3pm is _dramatic_.
- jessaustin 8y agoI'm just pointing out that the physical intuition you have from looking at a pegboard is incomplete. That's not the only way, either. The ozone layer is above all terrain and 99% of the atmosphere, so it receives direct unfiltered sunlight. Neither time of day nor latitude is relevant at this altitude. The only thing that blocks the sun is the rotation of the earth, which as we've observed has different effects in polar regions than in e.g. the equatorial region. Gosh physical intuition can be misleading! It's almost as if it would be better to take actual measurements of sunlight, like many scientists have done.
