dc.description.abstract Geostationary Ocean Color Imager (GOCI) has suffered from what is called inter-slot radiometric discrepancy (ISRD), which creates clear radiometric discontinuity across adjacent slots in the GOCI Level 1B (L1B) images. Preliminary analysis shows that large ISRD is observed in Bands 6 (680 nm) and 8 (865 nm), and the magnitude of radiometric inflation can be up to 20% in top-of-atmosphere (TOA) radiance. This paper proposes an image-based correction method, where the stray-light driven inflation in the L1B images is modelled by using the minimum noise fraction (MNF) transform. The experiment results showed that the proposed correction method reduces the ISRD in Band 6 and Band 8 to less than 2% in most of the cases, recovering the spatial continuity of natural variability across the slot boundaries.ary analysis shows that large ISRD is observed in Bands 6 (680 nm) and 8 (865 nm), and the magnitude of radiometric inflation can be up to 20% in top-of-atmosphere (TOA) radiance.
