There's no automation in measuring snowfall - the US National Weather Service has thousands of volunteers with rulers
Since 1890, the National Weather Service has relied on a network of volunteer observers, all strictly adhering to the NWS guidelines, to come up with snow measurement numbers over a region. There are over 8,700 cooperative observers across the country who send in their weather data to the NWS daily, some who have done it for over 75 years!
Snow measurement is inherently inexact, but attention to one’s surroundings and sticking to the guidelines help those of us who do it on a regular basis stay consistent—and with long-term weather records, consistency is arguably just as important as accuracy.
First, we do need to differentiate between snow depth and snow fall.
