Anomalous atmospheric spectral features between 300 and 310 nm interpreted in light of new ozone absorption coefficient measurements

Continuous scan data from the solar backscattered ultraviolet instrument on Nimbus 7, after known scattering and ozone absorption effects have been subtracted, reveals real structure in the atmospheric albedo between 300 and 310 nm, a region in which spectral anomalies have been reported in ground based observations. We find that these spectral anomalies are largely explained as structure at the one to five percent level in the ozone absorption coefficient as measured by Bass and Paur. Previous ozone absorption coefficient measurements were insufficiently accurate to resolve this structure.
