Effect of the half-width of the instrumental profile and the level of scattered light on the accuracy of satellite-borne ozonometric instrumentation
Abstract
The paper presents results of an investigation of the accuracy of satellite-borne ozonometric equipment for spectral channels in the 250-306-nm range. These channels are used to determine the vertical profile of ozone concentration via the UV backscatter technique. It is shown that the error associated with neglect of the half-width of the instrumental profile depends on the wavelength, and that, for certain channels, this half-width can be increased up to several nanometers without a significant increase in the error. At a light-scattering level of 0.0001 in the instrument, the error becomes inadmissibly high.
