NOAA's National Centers for Environmental Information (NCEI) and Air Resources Laboratory (ARL)
The U.S. Climate Reference Network (USCRN) is a system of climate observing stations developed by the National Oceanic and Atmospheric Administration (NOAA), with sites across the continental U.S., Alaska, and Hawaii. These stations use high-quality instruments to measure temperature, precipitation, wind speed, soil conditions, solar radiation, and more.
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 NOAA Air Resources Laboratory. NOAA’s National Centers for Environmental Information maintains and distributes the USCRN observations and derived climate products. The USCRN is also part of the multi-agency National Coordinated Soil Moisture Monitoring Network (NCSMMN).
