U.S. Climate Reference Network
The U.S. Climate Reference Network (USCRN) is a systematic and sustained network of climate monitoring stations with sites across the conterminous U.S., Alaska, and Hawaii. These stations use high-quality instruments to measure temperature, precipitation, wind speed, soil conditions, and more. Information is available on what is measured and the USCRN station instruments.
The vision of the USCRN program is to provide a continuous series of climate observations for monitoring trends in the nation's climate and supporting climate-impact research.
