N2 - In an effort to determine ozone measurement uncertainties associated with zenith sky radiation observations, a preliminary study involving radiative transfer calculations has been conducted to simulate ozone inference from Dobson spectrophotometer observations. By using a comprehensive radiative transfer algorithm, a model atmosphere, and a suitable set of ozone absorption cross sections, we have simulated, for a specific ozone profile and an ozone amount of about 350 Dobson units, the effects of cloud optical depth, cloud altitude, vertical distribution of ozone, temperature profile, and surface albedo on the total amount of ozone inferred by the Dobson procedure from zenith sky observations. Our simulations indicate that significant uncertainties may arise in determining ozone amounts from measurements of zenith sky intensity. -from Authors
