Abstract：Oceaniccarbon fluxconstitutesa critical component of the global carboncycleand fundamentalyinforms climate change modeling and prediction.The advent oflight detectionand ranging（LiDAR）remote sensing has gradualy revolutionizedoceaniccarbonfluxmeasurementsbyproviding highspatiotemporal resolutions，precision，andreal-time monitoringcapabies.Thisreviewevaluates recent advances in LiDAR-based monitoringof diurnal-nocturnal oceanic carbon flux dynamics.We examine the fundamental principles，methodological approaches，and technical challenges associated withLiDARapplications in carbon fluxquantficationacross theair-sea interface.Aditionally，weidentify knowledge gapsand propose futureresearch directions toenhance theeficacyof LiDARtechnology incharacterizing temporal variability in oceanic carbon sequestration.
