A steady-state ELMy H-mode profile data set of 68 DIII-D discharges and 74 JET discharges is fitted with an error of 7 - 8%. The advantages of a parametrization of the plasma profiles in terms of a semi-parametric representation, , are described. The shape of the temperature profile depends almost exclusively upon the size, R and , with a secondary dependence on the heating power. The density profile depends primarily upon with a secondary dependence on . The line-average temperature scales as instead of . The predicted ITER temperature is keV.
