The reference OMI tropospheric NO₂ product was reprocessed by new aerosol correction parameters retrieved from the 477 nm O₂–O₂ band over eastern China and South America for 2 years. These new parameters are from different and separate algorithms, allowing improved use of the 477 nm O₂–O₂ band. All the tested approaches improve the aerosol correction in the OMI tropospheric NO₂ product. We demonstrate the possibility of applying an explicit aerosol correction based on the 477 nm O₂–O₂ band.
