Incomplete contents:
In this paper we describe the development of our program to measure stratospheric trace gases, initially NO/sub 2/ and O/sub 3/ from our clean air site at Lauder, New Zealand (45 deg. S, 170 deg. E). Our method uses the differential absorption of scattered sunlight from the zenith sky in the wavelength region, 435-450 nm and we compare results obtained for two independent data reduction techniques; a point by point method and a least squares method. For our system and clean air conditions we conclude that the least squares method provides better results. (auth/HJP)
