Atmospheric Electricity and Atmospheric Pollution

Abstract

I HAVE read with especial interest the summary, in NATURE of April 5, p. 493, of Prof. Nolan's recent work on the relation between the potential gradient and the number of large ions in the atmosphere, because the problem he refers to is at least closely related to one that has been under investigation at Kew Observatory: namely, the relation between the potential gradient and the impurity in the atmosphere. In a recent paper (Roy. Soc. Proc. A, vol. 105, p. 311), discussing the observational results of 1921 and 1922, Mr. R. E. Watson and I found that the potential gradient at Kew is much enhanced by the impurity present in the air, being apparently on the average about double what it would be if the atmosphere were pure.
