U.S. Climate Reference Network (USCRN) - Quality Controlled Datasets

Associated Agencies

National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI)

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.

Temperature and Precipitation observations are available from monthly, daily, hourly, and sub-hourly datasets; soil moisture observations are available hourly.

How to

What can I do with these data?

  • Selected subsets of monthly, daily, hourly and sub-hourly (5-minute) USCRN/USRCRN data are available as text files for easy access by users ranging from the general public to science experts.

How do I use the site?

  • Select to view data at “Monthly,” “Daily,” “Hourly,” or “Sub-hourly.”
  • Use “FTP Client Access” under each section.
  • Data are offered by station


U.S. Climate Reference Network (USCRN) Datasets: including air temperature, precipitation, solar radiation, surface temperature, soil moisture and soil temperature data, are available. Files contain raw observations with quality flags, as well as calculated variables. Calculated data are shown only if a sufficient amount of source data passes its quality control tests; otherwise these values are set to a missing value.
