Abstract
The error and the vertical resolution of ozone density retrieval have been estimated as a function of the spectral resolution of the instrument. For a spectral resolution of 0.05cm-1 wavenumber, which is relevant to the IMG mounted on the ADEOS satellite, the tropospheric column density will be retrieved with an error of 10-15% when unknown parameters are restricted to the ozone density and the temperature. It is also suggested that the spectral resolution needs to be at least 0.05cm-1 wavenumber for the purpose of observing the tropospheric ozone without suffering the contamination by the stratospheric ozone.
