Scattered ultraviolet radiation in the 40 to 46 km altitude range is evaluated using an analytic, single-scattering description and results from the atmospheric ultraviolet radiance integrated code (AURIC). The calculations are compared with measurements obtained from a balloon-borne spectrometer at 1.5-nm resolution. The analytic approach is useful for approximating the angular and spectral dependence of scattered UV radiation; however, use of a single scale height to describe the vertical distribution of absorbers and scatterers leads to errors of 50% or greater at intermediate ozone opacities. Results from AURIC generally are compatible with the observations, particularly below 210 nm where large discrepancies have been noted in prior model/measurement comparisons. ¿ American Geophysical Union 1995
