The radiance of the earths daylit atmosphere at 2840 A has been measured with a satellite-borne radiometer as a function of latitude along the 2 oclock meridian and as a function of angle of insolation. The data are compared with the expected radiances calculated using three different ozone distributions. Using the relation between radiance and ozone concentration, the data also are analyzed to give the latitude distribution of the high altitude 35 km ozone. This analysis shows that the seasonal variation of the high altitude ozone appears to be about 6 months out of phase with the well known seasonal variation near the peak of the ozone profile maximum in late winter and minimum in late summer. The spectral distribution of the UV radiance calculated by a number of authors along with the present measurement and the data of other experimenters, are summarized and compared.
