A CoCoRaHS gauge (not mine): note how the funnel increases rain total by a 10-to-1 ratio, for easier reading. Weirdly, precipitation measurements are made in tenths of an inch.

OK, no excuses: It's time to become a precipitation-watcher for CoCoRaHS

The national precipitation-watching group CoCoRaHS is doing it annual membership drive, and as a volunteer for a couple of years I thought I'd toss in my two cents.

The group has 17,500 volunteers around the county, including 63 in New Hampshire, but the goal is to have one every square mile (!) so they have a long way to go.

This is a non-profit organization, so you have to buy your own rain gauge and snowboard (as in a board to collect snowfall on, not a board to ride the halfpipe) and then agree to upload measurements most mornings by 8 a.m. There's no membership fee, however.

It's surprisingly interesting even to a weather non-geek like me, especially the part about melting snow to see how much moisture it has. I feel much more connected to the weather than I ever have before. Plus, the data is getting widespread enough to be of actual value to meteorolgists and climate study; a real citizen-science project.

Check it out here, and think about joining. If nothing else, we want New Hampshire to win the annual which-state-gets-the-most-members contest!
