The up-down asymmetry of the type I plasma waves in the equatorial electrojet region during daytime is investigated. It is shown that the asymmetry is exhibited not only in the vertical direction but also is manifested in the oblique direction (24.6° off zenith). The results further indicate the effect of neutral winds on the phase velocities of type I plasma waves.
