2. The high degree of accuracy that is reached <strong>in</strong> <strong>the</strong> simulation of <strong>the</strong> R<strong>in</strong>g effect <strong>in</strong> GOME-type<br />
reflectivity measurements demonstrates that we can accurately model atmospheric rotational<br />
<strong>Raman</strong> <strong>scatter<strong>in</strong>g</strong> <strong>in</strong> backscattered sunlight. For this, our radiative transfer model and <strong>the</strong> derived<br />
<strong>in</strong>put solar spectrum are sufficient, <strong>in</strong>terpolation errors and undersampl<strong>in</strong>g errors can be<br />
avoided, and <strong>the</strong> mean residuals are reduced to <strong>the</strong> <strong>in</strong>strument noise level.<br />
3. Accurate cloud parameters can be retrieved from a comb<strong>in</strong>ation of O 2 A absorption band measurements<br />
and measurements of <strong>the</strong> near ultraviolet reflectivity cont<strong>in</strong>uum (350–400 nm). The<br />
R<strong>in</strong>g effect does not add significant <strong>in</strong>formation to <strong>the</strong> cloud parameter retrieval for this comb<strong>in</strong>ation.<br />
When O 2 A absorption band measurements are not available <strong>the</strong> R<strong>in</strong>g structures need<br />
to be <strong>in</strong>cluded to accurately retrieve cloud parameters.
