UHDAS proc (processed) data:

The proc directory contains one CODAS processing directory per instrument+pingtype. For the example of a ship with an NB150 and an OS38, the processing directories would be

  • nb150
  • os38bb
  • os38nb

Pingtypes (“bb” and “nb”) are processed separately because the singleping editing criteria are different, and because it is a useful diagnostic to compare the two datasets. Averaging and merging can be done by the user after postprocessing.

Processing directory

CODAS processing is documented in more detail here.

The contents of a CODAS processing directory are (in order of processing stages)

directories: pre-processing and metadata

  • config (metadata and processing configuration)
  • scan (charactierize timestamps, time range of data)
  • ping (default data location for pingdata, LTA, ENX (not UHDAS))
  • load (stage averages in the form of *.bin, *.cmd files)
  • adcpdb (contains *.blk (the CODAS files))

directories: CODAS processing

  • nav (positions : reference-layer smoothing of positions here)

  • edit (editing of averaged (CODAS) data; plot temperature)

  • cal
    • rotate (apply correction (time-dependent or constant))
    • watertrk (watertrack calibration calculation)
    • bottomtrk (bottomtrack calibration calculation)
    • rotate (testing effects of rotation; staging area)

directories: output for users

  • grid (staging lon/lat or time grid for data extraction)
  • vector (coarsly-gridded data, suitable for vector plots)
  • contour (finely-gridded data, suitable for contour plots)
  • png_archive (after “end cruise” on UHDAS installations, archive of png files (one per day) from the at-sea web site)

directories: quality and analysis

  • quality (staging)
  • stick (staging: frequency decomposition)

files

  • adcp_processing.html (link to local documentation if CODAS processing code is installed locally on the computer)
  • cruise_info.txt (metadata and processing documentation template for user)
  • CRUISEID.runlog (output of most recent quick_adcp.py command)
  • INSTPING_qpy.cnt (control file used to process these data)
