3.1.7. CODAS+UHDAS metadata

Depending on what information is desired, and the history of the processing directory, information about the data acquisition and processing may be found in a variety of places.

  • CODAS processing tree from unknown origin:

    A binary program lst_cfg lists time ranges and

    • transducer angle

    • bin size

    • blanking interval

    • bottom track on/off

    If quick_adcp.py was used, the listing will exist in the adcpdb directory as DBNAME.cnh (where DBNAME is the database prefix).

  • CODAS processing (after 2009) will include a file cruise_info.txt, with many of the processing parameters used

  • CODAS processing directories contain log files with

    • a history of phase and amplitude corrections applied

    • a history of calibration calculations

    • the time-dependent heading correction applied

    • averaged editing criteria applied

    • single-ping editing thresholds applied

  • acquisition and processing parameters are in the CODAS processing directories in a subdirectory “config”, containing such parameters as:

    • transducer angle, transducer depth

    • devices used for position, reliable heading, accurate heading

    • ensemble length

  • all UHDAS cruise distributions contain the log directory which has dialogs with the intrument, errors and warnings, time of stop/start

  • recent UHDAS at-sea directory

    A reports directory has information about calibrations, heading correction quality, and summary plots
