Data Synthesis Products
The Lamont-Doherty Earth Observatory (LDEO) database V2015 consists of approximately 10.5 million measurements of surface water pCO2 made over the global oceans during 1957-2015 have been processed to make a uniform data file in this Version 2015. The Surface Ocean CO2 Atlas (SOCATv5) of fugacity of carbon dioxide (fCO2): SOCAT version 5 has 21.5 million, in situ, surface ocean fCO2 measurements with an accuracy of better than 5 µatm and a WOCE flag of 2 (good) from 1957 to 2016.
