The difference between the true sea‐surface temperature and that inferred from satellite measurements of infrared radiances when viewing vertically through a cloud‐free atmosphere may be estimated to a useful accuracy for the 8–13μm radiometers of Defense Meteorological Satellite Program satellites. A simple parametric formula is developed that gives the difference to within ±0.6 K of that computed by a numerical method of solving the equation of radiative transfer. A comparison with data suggests that accuracies ⩽1.3K may be achieved relative to the actual value. Further work is necessary to confirm this accuracy because of an apparent discrepancy in the satellite data.
