SOCAT Quality Control Cookbook: for SOCAT version 7.

Abstract

This is the SOCAT quality control (QC) cookbook for SOCAT version 7. It is an update to the cookbook for version 1 (Olsen and Metzl, 2009) and version 3 (Olsen et al., 2015; Wanninkhof et al., 2013). It incorporates the revision of the data set quality control flags for version 3 (Wanninkhof et al., 2013), quality control procedures defined for versions 1 and 2 (Pfeil et al., 2013; Bakker et al., 2014), recommendations from the SOCAT Community Event on 23 June 2014 (SOCAT, 2014), and updates as discussed at the SOCAT event at ICDC10 in September 2017. There is no intention to retrospectively implement the revised quality control criteria for data sets in SOCAT versions 1-6. Consistent quality control and the adequate quality control comments fully justifying all quality control steps are extremely important (SOCAT, 2014).
