Abstract
This paper includes developments to a multi-sensor Atmospheric Correction (AC) that can be applied to marine and terrestrially-orientated medium resolution optical sensors, with a focus on the processing of imagery for coastal applications. The AC was originally developed for the airborne Compact Airborne Spectrographic Imager (CASI), and has since been expanded to include Com-pact High Resolution Imaging Spectrometer on the PRoject for On-Board Autonomy satellite mission (CHRIS-PROBA) with this paper detailing the extension to Landsat; examples shown are for the Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and Landsat 8 Operational Land Imager (OLI).

The preliminary results appear promising, but further research is needed. Although the suspended particulate matter (SPM) maps have realistic patterns, spectral plots comparing the Landsat results to MERIS and Moderate Resolution Imaging Spectroradiometer on the Aqua spacecraft (MODISA) atmospherically corrected data appear to show that the reflectance values are too high and the spectral shape indicates the BPAC is failing in some areas for the Landsat ETM+ data.
