I. Alongtrack datasets
I.1. Ship Track in the Southern Ocean (IX23). Grid Size : 6 km latitude along the Astrolabe mean ship track, 1993-2012. Details about the data origin, validation and gridding procedure can be found in Chaigneau and Morrow (J. Geophys. Res., 2002). Link to the SURVOSTRAL program.
I.2. Ship Track in the North Atlantic Ocean. Grid Size : 3° longitude (roughly along 60° N) x 3 months (1895-2009) or 1 month (1996-2011). Details about the data origin, validation and gridding procedure can be found in Reverdin (J. Climate, 17, 4571-4584, 2010), and Reverdin et al. (J. Geophys. Res., 107, C12, 8010, 2002). Download the files.
II. 3D Gridded Files
II.1. The Tropical Pacific Ocean, 1950-2009. Grid Size : 1° longitude x 1° latitude x 1 month. Domain : 120°E-70°W, 30°N-30°S, Details about the data origin, validation, and gridding procedure can be found in Delcroix et al. (Deep Sea Res., 58, 38-48, 2011). Download the 3D gridded file.
II.2. The Atlantic Ocean. 1970-2013. Grid size : 1° longitude x 1° latitude x 1 month. Domain : 95° W-20° E, 50° N-30° S, Details about the data origin, validation and gridding procedure can be found in Reverdin et al (Progress in Oceanogr., 73, 311-340, 2007).
II.3. The Atlantic Ocean. 1896-2013. Binned average yearly anomaly data in 32 sub-regional grid boxes. Domain: 75°W-10°E, 70°N-20°S. Information on the data origin, validation, gridding and properties of these time series is presented in Friedman et al. (Geophys. Res. Lett., 44, 2017, http://dx.doi.org/10.1002/2017GL072582).
