Abstract

The impact of vertical temperature gradients in the validation of the sea-surface temperature (SST) derived from the satellite radiometers are discussed. Comparable measurements taken in very low wind speed conditions, right panel, show that the time of best compensation occurs by 10:00 local sun time. The growth of the diurnal thermocline affect the skin effect to give a negative bias to the in situ measurements with respect to the skin temperature. The variability of the near-surface temperature structure in the oceans, obtaining an accurate determination of the uncertainities of the Advanced Along-Track Scanning Radiometer (AATSR) SST retrievals requires high quality measurements of the surface skin temperature.
