Depletion of stratospheric ozone by anthropogenic trace gases reduces the thermal forcing of the solar-driven atmospheric tides. The authors examine changes that have occurred in the diurnal and semidiurnal upward propagating tides since the onset of stratospheric ozone depletion. Estimated reductions in tide amplitudes since circa 1960 vary among the different modes but are generally less than about 10%. The most accurate measure of tidal strength for the main symmetric semidiurnal mode, the tropical semidiurnal surface pressure oscillation, has decreased about 3% since the beginning of ozone depletion, an amount that might be detected in the barometric record. Reductions in upper atmospheric tidal momentum fluxes are generally less then about 20%. The amplitudes of the solar forced tides will continue to decrease as ozone depletion continues.
