Quality Control
Hakai uses a unique tool to automatically QC the CTD profile data. The QCing tool relies on the IOOS_QC packaged and a series of in house tests.
The general QAQC workflow is summarized in the following diagram:
Automated Data QA QC (provisional data)
The automated QC tool is available and maintained within the hakai-profile-qaqc repository.
The tool runs essentially a series of tests available within the IOOS QC package and a series of in house tests.
The following configuration files are used to apply the different test to each individual variables:
- IOOS QC Config
- Hakai Tests Configuration
- Hakai Profiles Grey List: Hakai's Grey List overwrite any flag values obtained through the different test for a given one.
For a more detailed description of the different tests applied, please refer to the tests_description section.
Manual Review QA QC (research ready data)
A Manual Review Process is completed by a designated person which review each individual profiles and applies a flag to each individual variable profiles. Only the data associated with a AV flag value are then considered and presented through the Hakai Research Dataset.
The Hakai manually QCed log is retrievable through the Hakai Portal download page as CTD QC Tool sample type and within the hakai ctd.ctd_qc table within the Hakai Database.
