I. Alongtrack datasets

I.1. Ship Tracks in the Tropical Oceans. Grid Size : 1° latitude (for the N-S oriented tracks) or 2° longitude (for the E-W oriented tracks) x 1 month. Domain : 30°N-30°S. Details about the data origin, validation and gridding procedure can be found in Delcroix et al. (Deep Sea. Res., 52/5, 787-813, 2005). Download the mean monthly year and climatology.

Figure 1. Long-term mean sea surface salinity. Overplotted as heavy black lines are well-sampled shipping lines using SOOP naming convention (AX, IX, PX for Atlantic, Indian and Pacific lines respectively).

I.2. Ship Track in the North Atlantic Ocean 1996-2011. Grid Size : 3° longitude (roughly along 60° N) x 1 month (1996-2011). Details about the data origin, validation and gridding procedure can be found in Reverdin et al. (J. Geophys. Res., 107, C12, 8010, 2002). Download the files.

II. 3D Gridded Files

II.1. The Tropical Pacific Ocean, 1969-1995. Grid size : 10° longitude x 2° latitude x 1 month. Domain : 140°E-80°W, 30°N-30°S, Details about the data origin, validation, and gridding procedure can be found in Delcroix (J. Geophys. Res., 103/C9, 18,611-18,633, 1998). The gridded file can be obtained from the CD Rom entitled Three Decades of In Situ Sea Surface Salinity Measurements in the Tropical Pacific.
