Calibration information

Guide and relevant links for updating calibrations for various sensors

Calibration documents

Calibration documents are tracked in GitHub. Individual sensor calibrations can be found in the calibration folder, in individual folders by sensor.

NOTE: The collaborators folder has copies of calibrations for hydrophones owned by collaborator institutions (OSU and SWFSC).

NoteWISPR calibration

More detailed info on WISPR calibration (which is not tracked in the Seaglider operational files) can be found on the WISPR calibration page.

sg_calib_constants.m

Calibrations for operational and oceanographic sensors are recorded in the sg_calib_constants.m file. Each glider has its own sg_calib_constants.m and a back up should be made for the version used in each mission. See: Mission preparation: Updated “constants” files for more info.

A default example sg_calib_constants.m can be found in the sg000 subdirectory of basestation3.

RBR Tridente

The RBR Tridente writes out calibrated values so no calibration constants are needed in sg_calib_constants.m. The script tools/GetTridenteChannels.py will generate a calibcomm_tridente parameter to add to the sg_calib_constants.m file (for display in the plots and as documentation in the netCDF files).

Aanderaa optode

The optode’s calibration constants can be obtained from a selftest capture file (if mounted on a scicon), by using the tools/GetOptodeConstants.py script in basestation3. If not, the calibration sheet from the vendor has what you need.
