Abstract
The variation of spectral peak frequency and bandwidth as a function of source distance of atmospherics received during daytime from different directions is presented. Comparing these values with night-time values, it is noticed that the peak frequency is always higher for atmospherics propagated during daytime than those propagaged during night-time in any direction of propagation, the distance of propagation being the same. The bandwidth of the atmospherics received during the night is higher than that received during the day, for any direction of propagation, the distance of propagation being the same. These results are interpreted on the basis of attenuation rates during day and night.
