Galaxy cluster peculiar velocities can be inferred from high-sensitivity, high-resolution multiple-kequency observations in the 30 to 400 GHz range. While galaxy cluster counts and power spectra are sensitive to the growth factor, peculiar velocities are sensitive to the timederivative of the growth
