ASOS Surface System Log (SYSLOG)

ASOS Surface System Log (SYSLOG) is digital data set DSI-6402, archived at the National Climatic Data Center (NCDC). SYSLOG is an electronic systems messages logbook from the Automated Surface Observing System (ASOS). System Log Error Messages are generated by the ASOS when an error is detected by the continuous system self-test. When a faulty Field Replaceable Unit (FRU) is identified, the corrective action taken is to replace it. Messages not associated with the FRUs are for general information use only and require no corrective action. Error codes are assigned sequentially, unless otherwise specified. Major parameters in SYSLOG include ASOS station identification and time information, the message code, and a remarks field.
