 note = {With the view of studying the nature of atmospherics, the measurement of the intensity of atmospherics over the range from 10 kc/s to 30 kc/s is now put into practice at the Research Institute of Atmospherics, Nagoya Univ. The integration method has been employed in measuring the atmospherics output of narrow-band receivers. The band-width of the receivers was 500 c/s at 6 db down point and the time of integration about one minute. Diurnal and seasonal variations of the integrated level were described using the data from February to November 1953. From these results obtained, some suggetions to the D-region of ionosphere were recognized and discussed. The kown increase in the level of atmospherics on frequency 27 kc/s has been observed at the time of outburst on the sun, which occurred November 22nd, 1952 and October 15th, 1953.},
