Short summary

The NASA standard nitrogen dioxide (NO₂) version 4.0 product for OMI Aura incorporates the most salient improvements. It represents the first global satellite trace gas retrieval with OMI–MODIS synergy accounting for surface reflectance anisotropy in cloud and NO₂ retrievals. Improved spectral fitting procedures for NO₂ and oxygen dimer (for cloud) retrievals and reliance on high-resolution field-of-view-specific input information for NO₂ and cloud retrievals help enhance the NO₂ data quality.
