We all know our Pi Day storm last week was a big one.

Here in Thornton we recorded 10.8 inches. Downtown Denver reported 12.2 inches.

What will Denver’s official snow records show? A mere 5.7 inches. This is a direct result of the National Weather Service’s insistence on having Denver’s official measurements taken at Denver International Airport.

Data was collected in downtown Denver from 1872 through December 1948, then at the Stapleton Airport Office from January 1950 through February 1995. In March 1995, the service made the station at DIA the city’s official station for most meteorological observations. In 2008, they began taking official snowfall measurements out there.

Being so far from the Mile High City’s population center, the data collected there is entirely unrepresentative of what residents experience. Further, the move has skewed our climate records rendering comparisons to historical data invalid.  It is highly frustrating and is a significant issue which the National Weather Service dismisses.

Local television meteorologists have long railed against the change in station, most notably Mike Nelson of Denver 7. With this storm, Ashton Altieri of CBS 4 called the National Weather Service out on it.

This snowfall analysis across the Denver area from our good friends at @NWSBoulder proves (again!) why the rule about big cities having to officially measure precipitation at their airport is completely bogus.
