The cumulative probability of amplitude in the envelope of atmospheric noise has been measured at the output of a narrow-band receiver at 50 kc/s. The level of integrated atmospherics has been recorded at the output of the receiver at the same frequency. The band width of the receiver was about 1,000 c/s. The departure from a single logarithmic-normal distribution has been investigated. The description is given of the type of the amplitude distribution. The description is given of a calculation which has been done to determine the effect that the departures from a single logarithmic-normal distribution have on the total noise power. The curves derived from this calculation may provide a useful means in estimating the R.M.S. value of the noise amplitude. The description is given of a calculation which has been done to investigate the behavior or short-time fluctuations of the probability measured. The results may provide a means in estimating a pulse spacing of the larger amplitude. Various parameters have been derived from the amplitude distributions. The description is given of these parameters and the diurnal change of each parameter is shown, and the level of integrated atmospherics is compared with the R.M.S. value derived from the amplitude distribution.
