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

PDA Files

browse graphicStation Picture
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.

Purpose USCRN's primary goal is to provide future long-term homogeneous observations of temperature and precipitation that can be coupled to long-term historical observations for the detection and attribution of present and future climate change. Each station location is carefully selected to capture the representative climate regions of the nation. Data from the USCRN/USRCRN will be used in operational climate monitoring activities and for placing current climate anomalies into an historical perspective.
Use Limitations
  • Datalogger data is collected intermittently by a contractor (generally about once a year) and sent to the archive; this process can significantly delay the availability of the data. Datalogger data is incorporated into the USCRN system as soon as it is available from the archive.
