1. Where can I learn more about the SOCAT data collection?<\/strong>
\nA series of publications documents the public SOCAT data collection (Pfeil et al., 2013<\/a>; Sabine et al., 2013<\/a>; Bakker et al., 2014<\/a> and 2016<\/a>). A list of references is at the end of these FAQs.<\/p>\n

2. What datasets are included in the SOCAT data collection?<\/strong>
\nThe public SOCAT data collection has quality controlled surface ocean fCO\u2082 (fugacity of CO\u2082) values in a uniform format from the global oceans and coastal seas. Data coverage increased from the 1990s onwards.<\/p>\n

3. How should I cite the SOCAT data products?<\/strong>
\nVersion 2023: Bakker et al. (2016)
\nVersion 2022: Bakker et al. (2016)
\nVersion 2021: Bakker et al. (2016)
\nVersion 2020: Bakker et al. (2016)
\nVersion 2019: Bakker et al. (2016)
\nVersion 6: Bakker et al. (2016)
\nVersion 5: Bakker et al. (2016)
\nVersion 4: Bakker et al. (2016)
\nVersion 3: Bakker et al. (2016)
\nVersion 2: Bakker et al. (2014)
\nVersion 1 (synthesis data products): Pfeil et al. (2013)
\nVersion 1 (gridded data product): Sabine et al. (2013) and Pfeil et al. (2013)<\/p>\n

4. What are the agreed-upon SOCAT QC flags?<\/strong>
\nEach data set in SOCAT has been assigned a data set quality control flag (Pfeil et al., 2013; Bakker et al., 2014, 2016). Data sets with flags of A, B, C, D, or E are included in the public version 3. The synthesis and gridded files contain data sets with flags of A to D. Data sets with a flag of E are available in a separate synthesis file (Bakker et al., 2016).<\/p>\n

WOCE flags are applied to all fCO\u2082 values in the collection. A WOCE flag of 2 means \u2018good\u2019, a WOCE flag of 3 means \u2018questionable\u2019, and a WOCE flag of 4 means \u2018bad\u2019. The synthesis and gridded files contain fCO\u2082 values with a WOCE flag of 2. fCO\u2082 values with WOCE flags of 3 and 4 can be accessed in the individual data set files and via the Data Set Viewer (Bakker et al., 2016).<\/p>\n

5. How was fCO\u2082 computed for data sets that reported other CO\u2082 parameters?<\/strong>
\nThe procedure by which the variable fCO2_rec (the recomputed fCO\u2082) was obtained is described in Pfeil et al. (2013) and Bakker et al. (2014, 2016). The variable fCO2rec_src, available in the SOCAT synthesis data product, contains an integer (1-14) that indicates which pathway was used for the calculation of each fCO2_rec value.<\/p>\n

6. How can I get a quick overview of the SOCAT data collection?<\/strong>
\nThe SOCAT Data Set Viewer and the Gridded Data Viewer provide interactive access to the SOCAT data collection. Data can be selected by e.g. year, region, vessel and season. Making maps and property-property plots is straightforward. Access is via the links on the different SOCAT version pages (e.g. for version 2022<\/a>) under the Interactive<\/em> header. More information on these Data Viewers follows below.<\/p>\n

7. How can I download all or parts of the SOCAT data collection?<\/strong>
\nThe data collection is available as downloadable individual data set files, as regional and global synthesis files and as gridded files. Use the links on the different SOCAT version pages (e.g. for version 2022<\/a>) under the Data Files<\/em> header.<\/p>\n

Selections of data sets and gridded data can be downloaded via the SOCAT Data Set Viewer and the Gridded Data Viewer (see FAQ section below). Access is via the links on the different SOCAT version pages (e.g. for\u00a0version 2022<\/a>) under the\u00a0Interactive<\/em>\u00a0header.<\/p>\n

A variety of file formats is available for download. A full description of these data products is in Pfeil et al. (2013), Sabine et al. (2013) and Bakker et al. (2014, 2016).<\/p>\n

8. How can I get the SOCAT data collection into Matlab?<\/strong>
\nMatlab code for reading the SOCAT synthesis files and gridded files is available via the\u00a0different SOCAT version pages (e.g. for\u00a0version 2022<\/a>) under the\u00a0Instructions and MATLAB scripts<\/em>\u00a0header under the\u00a0Synthesis and Gridded Files from NOAA NCEI<\/em> dropdown.<\/p>\n

9. How can I access the SOCAT data collection in Ocean Data View (ODV)?<\/strong>
\nThe SOCAT synthesis and gridded files are available in Ocean Data View via the \u2018Download Data\u2019 link on the SOCAT start page (https:\/\/www.socat.info<\/a>).<\/p>\n

10. What is the SOCAT Fair Data Use Statement?<\/strong>
\nThe SOCAT Fair Data Use Statement is available here<\/a>. In summary, we expect that users of SOCAT data products:<\/p>\n
