Automated Surface Observing System Error Logs

ASOS Surface System Log (SYSLOG) is a digital data set of electronic system messages and error codes from the Automated Surface Observing System. The log is generated by continuous system self-tests and includes station identification, timestamps, message codes, and remarks. It is archived at the National Climatic Data Center under DSI-6402 and originates from NOAA NCEI.

Use Cases

• Analyzing patterns in error message codes to predict hardware failures in Field Replaceable Units (FRUs).
• Correlating station identification and time information with environmental events to assess system robustness.
• Classifying remarks field text to distinguish between critical FRU errors and general information messages.
• Modeling the sequential assignment of error codes to detect anomalies in system self-test reporting.

Strengths

• Data originates from the authoritative National Climatic Data Center (NCDC) archive.
• Logs are generated by continuous, automated system self-tests, ensuring consistent data capture.

Limitations

• The specific number of stations, rows, and temporal coverage is unknown.
• Data may be biased towards stations with ASOS hardware, limiting geographic representativeness.
