A NEW METHOD FOR THE DETERMINATION OF THE VERTICAL DISTRIBUTION OF OZONE FROM A GROUND STATION

Abstract

A new method for determining the vertical distribution of ozone, utilizing only surface observations, has been developed. Infrared and ultraviolet observations are used to complement one another. The theoretical background of the method is discussed in detail, and the techniques of its application are described. Also presented are the results of applying the method to data collected in the seven months beginning February 1955 (124 days' observations). There are definite seasonal trends in the distributions, which are not related in any simple way to the total amount of ozone. The ozone is lowest at times of passages of troughs aloft. Ozone densities at low levels are greatest when surface pressure is lowest.
