In order to avoid the replication crisis that's plaguing the rest of science, where does one submit a grant proposal to independently verify this scientific discovery?

My guess is that "best" describes the ease and frequency of sighting rainbows. Businger explains this is because orographic precipitation, climate, and clear line of sight due to terrain, make it highly likely to spot a rainbow at least twice a day (early morning and an hour or so before sunset), when the sun is 38 degrees above the horizon on either side of the island. This means you should be able to sight a rainbow closer to the windward side of the island in the morning, and another rainbow closer to the leeward side in the late afternoon. When you take all of these factors into account (more are described in the article), Businger's claim isn't so far off. Given the right conditions, is there anywhere else in the world where you can spot at least two different rainbows every day like clockwork?

Well, of course. No question is more scientific than "which rainbows are better than which other rainbows?"

Brother Iz knew the whole time.

I captured this one in NJ in 2015:

(38.993472° -74.839455°)

I pulled off the Garden State Parkway to take the picture. It’s the finest rainbow I’ve ever seen. Sadly was unable to find an unobstructed view.

There is of course the triple rainbow that famously brought a man to tears in Hawaii a decade ago.

No matter where it is, rainbows are amazing. Just thinking about how light gets scattered, it's just amazing of universe

I'm happy that somewhere out there there are scientists studying such really important problems.

My rainbow is better than your rainbow

It is so frustrating to get "Error 403 Forbidden" when visiting from EU. Using US VPN, the page loads fine.

It's been 3+ years to figure out GDPR stuff. 403 Error with zero apologies is just terrible.
