Time-series-of-SST-depth-between-01-and-5-m-in-the-Arabian-Sea-showing-significant.png
Time series of the SST at depths between 0.1 and 5 m in the Arabian Sea showing significant diurnal variability. The Foundation SST (SST fnd ) is shown as a strong solid line and corresponds to a pre-dawn SST after the decay of diurnal stratification (The GHRSST-PP International Project Office 2008)

Idealized temperature profiles of the near-surface layer (10-m depth) of the ocean. Schematic diagram showing (a) idealized night-time vertical temperature deviations from SST fnd (foundation SST) and (b) idealized day-time vertical temperature deviations from SST fnd in the upper ocean (The GHRSST-PP International Project Office 2008; Donlon et al. 2002)
