U.S. Climate Reference Network

The National Oceanic and Atmospheric Administration (NOAA) created the 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.

USCRN stations are managed and maintained by the Atmospheric Turbulence and Diffusion Division of the Air Resources Laboratory, NOAA Office of Oceanic and Atmospheric Research. The National Centers for Environmental Information maintains and distributes the USCRN observations and derived climate products.

The USCRN record of the Average Temperature Anomaly in the U.S. shows no warming trend since the network was established in 2005.
