Central Park Conservancy will take over snowfall measurements

The National Weather Service announced today that the Central Park Conservancy will take over measuring snowfall during the winter of 2015-2016. This marks and end of a 22-year run for the Central Park Zoo, where snowfall has been measured since 1993. The National Weather Service trained 20 or more individual employees at the Central Park Conservancy over the past several months in order to make the transition as easy as possible, and to improve accuracy of snowfall reporting in New York City.

Measurements at the Central Park Zoo had come under significant scrutiny over the past several winters, . This came to a head in 2015, when the National Weather Service retroactively adjusted snowfall totals that were reported by the Central Park Zoo. Three snowfall events (January 6th, January 24th, and February 2nd) were adjusted to increase snowfall amounts based on surrounding observations.

In prior years, the meteorological community was often left wondering why Central Park was reporting lower snowfall totals than surrounding stations. Frequently, Central Park’s snowfall observations would be lower than LaGuardia, Teterboro, and Newark, despite similar or or even more adverse conditions at surrounding locations.

Central Park has one of the oldest standing snowfall and weather observation records, dating back to 1869.

The official statement from the National Weather Service is attached below:
