The Atmospheric Radiation Measurement (ARM) user facility is providing data in netCDF format from the U.S. Climate Reference Network (USCRN), a network of climate stations being developed as part of a National Oceanic and Atmospheric Administration (NOAA) initiative. With 101 stations installed (100 in the United States and 1 in Canada), the USCRN provides long-term observations of temperature and precipitation that can be paired with long-term historical observations for the detection and attribution of present and future climate change. The two main observations are hourly average surface air temperature and hourly total precipitation. Data are available for the Barrow station from 2002-08-09 to the present and for two Stillwater stations from 2002-03-12 to the present.
