Abstract: The quantitative remote sensing monitoring of Fengyun satellite for Marine environmental disasters (ulva prolifera, red tide and oil spill) should to be improved. This paper uses the MERSI data of FY-3D satellite data, as well as some high-resolution satellite data,to explore methods to solve the two technical difficulties of atmospheric correction and cloud detection. Based on the spectral characteristics of ulva prolifera, red tide and oil spill, relevant monitoring algorithms were established for identifications of ulva prolifera, red tide and oil spill, and there were good monitoring performances in corresponding cases.
Key words : ulva prolifera;red tide;oil spill;satellite remote sensing monitoring;FY-3D satellite

海洋環(huán)境災(zāi)害如滸苔、赤潮溢油,給人類生產(chǎn)生活帶來嚴重影響,需要及時發(fā)布監(jiān)測預(yù)警。衛(wèi)星資料具有高時空分辨率、觀測范圍廣的特點,能夠監(jiān)測沒有常規(guī)資料的海洋上空。滸苔、赤潮和溢油與海水之間存在光譜特征差異,使得衛(wèi)星遙感監(jiān)測海洋環(huán)境災(zāi)害事件成為可能。在數(shù)據(jù)質(zhì)量方面,風云三號D星中分辨率光譜成像儀Ⅱ型(FY-3D MERSI-II)數(shù)據(jù)質(zhì)量完全可以與國際上同類先進儀器數(shù)據(jù)相比[1-3],在遙感監(jiān)測方面,風云三號衛(wèi)星資料[4-6]在天氣分析和陸地環(huán)境遙感監(jiān)測等方面業(yè)務(wù)應(yīng)用較多,但海洋環(huán)境監(jiān)測能力則有待提升。

為了加強海洋環(huán)境監(jiān)測建設(shè),國家衛(wèi)星氣象中心面對海洋經(jīng)濟發(fā)展、海洋生態(tài)環(huán)境保護和國防軍事活動保障等方面的迫切需求,研制完成海洋環(huán)境監(jiān)測分析服務(wù)軟件,并陸續(xù)在國家衛(wèi)星氣象中心和山東省氣候中心部署應(yīng)用,在業(yè)務(wù)中實現(xiàn)近海海域赤潮監(jiān)測、滸苔監(jiān)測及面積統(tǒng)計、海上石油溢油監(jiān)測等功能。
