CoCoRaHS Versus NWS Gauge
Cutty Sark Sailor:
--- Quote from: TheBushPilot on December 05, 2022, 12:07:57 PM ---Why does CoCoRaHS use the 4" gauge instead of the 8" NWS standard size? Or does size matter?

Thanks for sharing Cutty.
That new option hasn't made it here yet, but we do get a good price on the existing CoCoRaHS approved http://www.shopcocorahs.ca/
How would it do for snow core sampling? We had snow/ice combination a few days that resulted in ice/snow of over 5 cm and it was very difficult to get the current outer tube to get through the crust. Looks like the new type has some vulnerable parts on the side.
Enjoy,
Paul

I did not have the opportunity to try a snow core. Indications from others are 'no problem'.
Not sure what would be 'vulnerable' parts on the side.... as I said when I summed up my testing:
"A comment on the material: Based on specifications, I believe the material used will have longer clarity life using its UV enhanced material. This state-of-the-art construction almost felt 'flimsy' at first, because of appearance and material, compared to the 'other name', but it is at least as strong-- maybe stronger. Impressive."
...And it's breeze to get out of bracket if freezes... gentle tap got 'er loose 4 times.
