Long Wave Radio Reception and Atmospheric Ozone

Abstract

FOR some time past, efforts have been continuously made to find out the relation between the signal strength of distant radio stations and magnetic and meteorological elements of the earth. The results obtained by Austin and Pickard have shown that there is some connexion between radio reception and solar phenomena, such as those due to the spots on the sun. The method adopted has been purely statistical, due to the very nature of the circumstances. Clayton, in his letter in NATURE of July 30, 1927, p. 153, pointed out the possible existence of a relation between solar radiation, sunspots, and the amount of ozone present in the air, as determined in northern latitudes by Dr. Dobson and his associates.
