United States Climate Reference Network (USCRN) Raw Observations from Datalogger

Published by DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 20, 2025 | Last Modified: 2000-11-15T00:00:00.000+00:00

Datalogger files are raw USCRN data. However, instead of being collected via satellite, the raw data are collected from station dataloggers (also referred to as PDAs--Personal Digital Assistant) in the field during site maintenance visits by NOAA/ATDD engineers. These data are uploaded to a site at Oak Ridge National Lab from where they are pulled by NCEI. These raw data are received as CSV formatted files--detailed documentation are required to read the data and will be provided to ingest. These files may not be available until months after the included observations are made. These data are considered of higher quality than USCRN Raw/streamed data.
