Preliminary study of atmospheric correction of the marine airborne multi-spectrum scanner (MAMS): a case study in East China Sea

China Marine Surveillance is equipped with the modern aerial equipments for marine law-execute with the advantages of functioning agilely and larger surveillance coverage, which provide the powerful safeguard for the harmonious and sustainable development of Chinese coastal economy. Onboard the plane, the marine airborne multi-spectrum scanner (MAMS), made by Shanghai Institute of Technology and Physics CAS, is an important equipment. In this paper we will briefly introduce a flight experiment in East Chinese Sea using MAMS at first. To retrieve the quantitative information from MAMS data, atmospheric correction is a necessary step. So we will focus on applying atmospheric correction algorithm MODTRAN to the MAMS airborne ocean color remote sensing data. Then case study of Zhoushan sea area in East Sea will be discussed. The result demonstrates that the MODTRAN is insufficient in retrieving sea surface reflectance when apply it directly for the low-altitude airborne remote sensing in Chinese coastal area.
