Yeah i just recently read through NWS' 14 page COOP snow measurement guidelines PDF. On the surface you wouldn't think that it's that complicated, but theres so many different variables and things to consider. I guarantee the average person who sends a public report thinks, "how can that be? you just stick a ruler in the ground after it snows and thats it"
We have all these different programs with different standards with CoCoRaHs, CO-OP, Skywarn..etc. It would be nice if there was just one umbrella for everything
I ran across this other program when looking at old PNS from the late 90s and early 00s that i can't figure out what it is. Something called SWIN observers? I tried searching but couldn't find anything. I was thinking maybe it was an acronym for SkyWarn Independent Network or something like that? Or it's something completely different that's obsolete.
