U.S. Climate Reference Network

[2] It provides the United States with a reference network that meets the requirements of the Global Climate Observing System.

The result was the USCRN that collects major climate variables, which are then assembled by the National Centers for Environmental Information into a database and made available, free of charge, to the public.

[6] The USCRN is managed and maintained by the Surface-Atmosphere Exchange, a department of the Air Resources Laboratory, a division of NOAA Research.

The National Centers for Environmental Information maintains and distributes the USCRN database of observations and derived climate products.

[7] Each station is positioned in a pristine site which is representative of the climate of the region and expected to remain free from development over coming decades, in order to avoid, for example, possible urban microclimate interference.
