More than a century of weather records
The first monthly weather summary, recorded in January 1896 by Alfred K. Smiley, the first official observer of the Mohonk Lake Cooperative Weather Station.
A preliminary analysis of the Preserve’s weather data shows that the average temperature has risen about two degrees over the past 119 years.
Composed of more than 40,000 days of weather observations, these records comprise the collection of the Preserve’s Mohonk Lake Cooperative Weather Station, established in 1896 by the U.S. Weather Bureau (now the National Weather Service).
Weather readings at Mohonk began in the mid-1880s, taken by the Smiley family, founders of the neighboring Mohonk Mountain House, and are now continued by Preserve research staff. Beginning in the late 1970s, data collection expanded to include regular monitoring the pH of precipitation, lakes, and streams.
Why is this data important?
To identify the extent of global climate change, researchers need access to reliable data covering the longest period possible. The Preserve’s weather data is dependable because the station has been in the same, comparatively stable location for over a century and the same protocol has been followed by the relatively few people involved in collecting the data.
