Measuring snow
The correct way to measure snow
Sometimes not a “no-brainer”!
![Page 17: The Forgotten Blizzard of 1886 - Are our climate records better today?](https://reader036.fdocuments.net/reader036/viewer/2022062803/568146a0550346895db3bb37/html5/thumbnails/17.jpg)
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
