Abstract: Retrieval uncertainty estimates for vertical tropospheric NO2 columns based on theoretical error source discussions combined with actual Global Ozone Monitoring Experiment (GOME) observations are presented. Contributions to the total retrieval uncertainty are divided into three categories: (1) errors caused by measurement noise and spectral fitting, affecting the slant column density, (2) errors related to the separation of stratospheric and tropospheric NO2 affecting the estimate of the stratospheric slant column, and (3) errors due to uncerta...
