Abstract: Principal component analysis has been used to determine the number of linearly independent pieces of information that may be inferred from Umkehr observations. The analysis indicates that there are at most four such pieces ...

Abstract: This paper is concerned with a preliminary study of the feasibility of determining total atmospheric ozone from satellite measurements of the solar ultraviolet radiation diffusely reflected by the earth's atmosphere. The ...

Abstract: The optimum statistical inversion technique is applied to the evaluation of Umkehr observations from Arosa (46.5N, 9.4E), Aspendale (38.0S, 145.IE) and Tallahassee (30.2N, 84.2W). A Priori statistical information on the ...

Abstract: Total ozone is estimated from Nimbus IV satellite measurements of the attenuation of backscattered radiances at wavelengths between 3100 and 3400 Å. A measurement of the backscattered radiance at 3800 Å, outside the O3 ...
