Summary:Radio noise data obtained with the CRPL model ARN-2 noise recorder at Byrd Station, Antarctica, during blizzards are analyzed. The noise power data are used to determine some of the characteristics of snow static in the frequency range 0.51 to 20Mc/s. The frequency dependence of snow static and its relation to wind speed are established. Magnitude of the noise intensity decreases with increasing frequency from 0.51 to 5Mc/s. Snow static during blizzards is apparently caused by point discharge when the electrostatically charged blowing snow particles strike the unshielded receiving antenna. It is shown that measurements utilizing radio techniques with exposed antennas may be seriously affected by snow static during Antarctic blizzards.
