Figure 1From: The salinity signature of the equatorial Pacific cold tongue as revealed by the satellite SMOS missionAnnual mean distribution of (a) SST and (b) SSS from the SMOS mission and (c) timeseries diagram between 8°N and 8°S along 110°W from the SMOS mission (background) and in situ observations from the Argo floats (circles) observed during the 2010–2013 period. On the top figure the dark line represents the 22.5 kg/m3 value and the thin black line marks the limits of the Wyrtki box. In the middle panel the thin black line is the 35.2 isohaline. Unit for temperature is in °C.Back to article page
