The LDEO (Takahashi) Surface pCO2 database V2015 is now available at CDIAC

The LDEO (Takahashi) Surface pCO₂ database V2015 is now available at CDIAC: http://cdiac.ornl.gov/oceans/LDEO_Underway_Database/. 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. Measurements made in open oceans as well as in coastal waters are included. The data assembled include only those measured using equilibrator-CO₂ analyzer systems, and have been quality-controlled based upon the stability of the system performance, the reliability of calibrations for CO₂ analysis and the internal consistency of data. The documentations for the previous versions (V1.0, V2007, V2008, V2009, V2010, 2011, V2012, V2013, and V2014) of our database are available at CDIAC http://cdiac.ornl.gov/ftp/oceans/LDEO_Database/
