Quality Control test are based on code developed at IOOS https://github.com/ioos/qartod

Daily raw files are run through quallity control (above table) and appended with quality control flags to yearly NetCDF files.
NetCDF files are available from http://sccoos.org/thredds/ and http://sccoos.org/erddap/
