Measuring snow

The correct way to measure snow

Sometimes not a “no-brainer”!

You will need two SNOW BOARDS. Approx. 3 ft X 3 ft and painted white.

One board never gets swept (this one is for continuous snow depth)

•The other board gets swept during snow event every 6 hours. Wiggle room here!!

•The total snowfall for event is the Summation of all 6 hourly measurements

First order climate locations

• At airports—MANY challenges• Poor siting-NWS has no say where they are.• Too many obstructions• Too few acceptable locations to measure.• CENTRAL PARK BETTER—open sky, natural terrain,

24/7 coverage, yearly training.• Doing it here since winter of 1996-97
