Turbulence production and dissipation profiles averaged over a period of forced flow pulsations have been obtained experimentally across the boundary layer, developing on a channel wall under forced periodic freestream unsteadiness. The experiments have been conducted in a wide range of dimensionless numbers β=0.03-0.28 and Strouhal numbers St=2.99-64.2 that characterize relative amplitude and frequency of flow pulsations. The parameters have been estimated based on the instantaneous velocity fields, measured by 2D optical method of Smoke Image Velocimetry (SIV). Turbulence dissipation and production profiles plotted in wall coordinates have been compared to the corresponding steady flow profiles. In the considered ranges of dimensionless numbers, the insensitivity of turbulent dissipation profiles to periodic flow unsteadiness has been established, and conclusion on similar insensitivity of turbulence production profiles drawn on the basis of point measurements and DNS has been confirmed
