“…Hence, the variation in the percentage transmission of a filter as a result of swaying of the apparatus container would be largest for the filter opposite to the uncovered opening in the disk and could be detected and corrected by comparing the relative transmissions of two adjoining filters, or the percentage transmissions of the two filters adjoining the unobstructed opening (10) in the disk. This is evident in the sequence of rotations A, B, C, D, in figure 5, where all the points lie on the average CUlve (A and C) or some points do not fall on the average curve (in B and D).…”

“…The object of the present paper is to present the results of a preliminary attempt to determine radiometrically the spectral quality and total intensity of the ultraviolet solar radiation of short wave lengths, in the stratosphere, and thereby obtain a check on the spectrographic determinations of the distribution of ozone (made by Dobson, Goetz, Regener, and others), which are somewhat in disagreement in that in Regener's [8] balloon ascents a considerable portion of the ozone appeared to be diffused to somewhat lower elevations than recorded in the two ascents reported upon by O'Brien [11] and by Mohler [10]. As will be shown presently, both sets of observations may be correct.…”

A description is given of a photoelectric cell and filter type of ultraviolet-intensity meter [IF which is combined with an audio-frequency generator and radio transmitter and transported aloft by means of unmanned balloons.The radio-frequency wave is modulated by the response of the photoelectric cell, the response being proportional to the intensity of the incident ultraviolet rays. The height of the balloons is indicated by a radio barograph. The radio signals giving the altitude of the apparatus and the ultraviolet intensities are received and recorded graphically at a ground station.Six balloon ascensions were made during the latter part of June and the early part of July 1937. Altitudes up to about 80,000 ft (24 km) were attained, but owing to the weakness of the signal and the consequent interference by noise strictly quantitative data were obtained only to about 64,000 ft (19 km).Below 14 km the transmissions of ultraviolet throu gh the filters remain fairly constant, indicating but little change in the spectral quality of the shortest wave lengths. At a height of about 14 km the transmissions of the filters begin to decrease, indicating a selective increase in intensity of ultraviolet of the shortest wave lengths, as a result of a decrease in the amount of ozone above the apparatus.Between 14 and 19 km the filters show an unmistakable decrease in transmission, indicating that the apparatus had passed through an appreciable portion of the ozone layer, variously estimated at 15 to 30 percent of the superposed ozone, the lower value being in good agreement with previous explorations (in 1934), taking into consideration the latitude and the season of the year.At the highest altitudes attained the intensity of the ultraviolet radiation in the band of wave lengths shorter than 3132 A was about 3 times the value observed at sea level. This spectral band includes, of course, also wave lengths not observed at sea level. CONTENTS Page
