A vertical phase shift of the diurnal harmonic of geopotential height S1(Z) in the lower troposphere of low latitudes is shown by a comparison of diurnal harmonic of surface pressure at two surface stations that have an elevation difference close to 4 km. It is inferred from longitude-height cross sections of S1(Z) that this vertical phase shift is caused by the differential response of the lower and mid-upper troposphere to the diurnal variation of radiative heating/cooling.
