Aerosol　Optical　Depth　(AOD)　is　vital　for　assessing　air　quality　and　climate.　Nighttime　lights　(NTL)　provide　a　new　data　source　for　urban　AOD　inversion,　but　current　NTL　data　suffer　from　low　spatial　resolution,　limiting　detailed　AOD　studies　in　smaller　urban　areas　and　hindering　high-precision　AOD　algorithms.　This　study　introduces　methods　for　retrieving　AOD　using　Glimmer　Imager　(GLI)　data　from　the　newly　launched　SDGSAT-1.　Three　methods　were　proposed:　the　standard　deviation　method,　look-up-table　method,　and　collaborative　inversion　method　with　VIIRS　Day　Night　Band　(DNB)　data.　Applied　to　Beijing,　these　methods　produced　a　10　m　resolution　AOD　product.　The　look-up-table　method　achieved　the　highest　correlation　(R　=　0.8876)　compared　to　the　standard　deviation　(R　=　0.8224)　and　collaborative　inversion　(R　=　0.8322)　methods.　The　look-up-table　method　performed　best　with　ample　data,　while　the　collaborative　inversion　method　proved　more　reliable　with　limited　data.　These　findings　demonstrate　the　effectiveness　of　SDGSAT-1　GLI　data　in　accurately　retrieving　nighttime　AOD,　offering　significant　potential　for　monitoring　urban　pollution.　©　2024　The　Author(s).　Published　by　Informa　UK　Limited,　trading　as　Taylor　&　Francis　Group.
