Project Overview

These datasets are from the weather stations at the Mohonk Preserve. The Mohonk Preserve is one of 14 sites recording data in the Hudson Valley as part of the Environmental Monitoring and Management Alliance (EMMA). 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.


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. Also to monitor climate change in support of the Environmental Monitoring & Management Alliance (EMMA), a regionally-coordinated ecological monitoring network dedicated to informing sustainable management practices and natural resource conservation through scientific research while engaging the public in environmental protection.
