【摘要】：隨著經(jīng)濟(jì)的不斷發(fā)展，環(huán)境污染問題逐漸浮出水面，近十幾年來，環(huán)境污染問題已經(jīng)成為國際社會不可不提的重要課題，環(huán)境污染給人類生活與身心健康帶來的危害也越來越嚴(yán)重，解決環(huán)境污染問題刻不容緩。 就中國本身而言，自改革開放以來，中國試圖貫徹“可持續(xù)發(fā)展”的發(fā)展戰(zhàn)略，但實(shí)際情況卻并不十分理想，嚴(yán)重的環(huán)境問題是制約中國經(jīng)濟(jì)發(fā)展的重要因素，所以環(huán)境問題的監(jiān)測與治理成為中國尋求發(fā)展道路上不可忽視的問題。相較國外而言，我國對環(huán)境污染的監(jiān)測特別是大氣污染的監(jiān)測起步較晚，傳統(tǒng)的監(jiān)測站點(diǎn)和儀器已經(jīng)不能滿足現(xiàn)今大氣污染的多變性，衛(wèi)星遙感以其數(shù)據(jù)的廣泛性、圖像的穩(wěn)定性和信息獲取的快速性迅速成為大氣污染監(jiān)測的主要手段。我國風(fēng)云1、2、3號衛(wèi)星的成功發(fā)射以及后續(xù)資源衛(wèi)星、氣象衛(wèi)星以及海洋衛(wèi)星三大遙感衛(wèi)星系列的成功組建也標(biāo)志著我國在衛(wèi)星遙感監(jiān)測大氣污染領(lǐng)域的努力和成就。 本文選取上海市為研究源，運(yùn)用V5.2算法和6S傳輸模型作為研究方法同時結(jié)合MODIS L1B數(shù)據(jù)對上海市氣溶膠衛(wèi)星遙感圖像進(jìn)行反演，對上海市氣溶膠光學(xué)厚度進(jìn)行研究。 首先，本文將會從MODIS L1B數(shù)據(jù)的組成與結(jié)構(gòu)進(jìn)行分析，闡述衛(wèi)星遙感氣溶膠光學(xué)厚度的數(shù)據(jù)來源，并簡要介紹6S傳輸模型的形成機(jī)理，同時對V5.2算法進(jìn)行簡單闡述，為后續(xù)研究提供背景和數(shù)據(jù)支持。 其次，本文將會從上海市氣溶膠光學(xué)厚度反演的可行性進(jìn)行實(shí)驗(yàn)分析，，實(shí)驗(yàn)會選取2010-2011年內(nèi)的八天作為研究數(shù)據(jù)源，對其進(jìn)行AOD反演，并將反演值與AERONET觀測值做出對比。從精確度上分析反演的可行性。 最后，本文將會在可行性存在的情況下，選取上海市周邊城市作為對比數(shù)據(jù)源進(jìn)行氣溶膠光學(xué)厚度反演，并結(jié)合反演值闡述上海市氣溶膠濃度空間相關(guān)性。
[Abstract]:With the continuous development of economy, the problem of environmental pollution has gradually surfaced. In the past ten years, the problem of environmental pollution has become an important topic that must be raised by the international community. Environmental pollution brings more and more serious harm to human life and physical and mental health, so it is urgent to solve the problem of environmental pollution. As far as China itself is concerned, since the beginning of reform and opening up, China has tried to implement the development strategy of "sustainable development," but the actual situation is not very satisfactory. Serious environmental problems are important factors restricting China's economic development. Therefore, the monitoring and management of environmental problems has become a problem that can not be ignored on the road of China's development. Compared with foreign countries, the monitoring of environmental pollution in China, especially the monitoring of air pollution, started late, the traditional monitoring stations and instruments can no longer meet the variability of air pollution, satellite remote sensing data are extensive. The stability of images and the rapidity of information acquisition have become the main means of air pollution monitoring. The successful launch of Fengyun 1 / 2 and 3 satellites and the successful establishment of three series of remote sensing satellites such as the following resource satellites meteorological satellites and marine satellites also marks the efforts and achievements of our country in the field of satellite remote sensing monitoring of atmospheric pollution. In this paper, using V5.2 algorithm and 6S transmission model as the research method, Shanghai aerosol satellite remote sensing image is retrieved with MODIS L1B data, and the aerosol optical thickness in Shanghai is studied. First of all, this paper will analyze the composition and structure of MODIS L1B data, explain the data source of satellite remote sensing aerosol optical thickness, and briefly introduce the formation mechanism of 6S transmission model, and the V5.2 algorithm. To provide background and data support for follow-up research. Secondly, the feasibility of aerosol optical thickness inversion in Shanghai will be analyzed experimentally. Eight days from 2010 to 2011 will be selected as the data source for AOD inversion, and the inversion values will be compared with AERONET observations. The feasibility of inversion is analyzed in terms of accuracy. Finally, under the condition of the feasibility, the aerosol optical thickness inversion will be carried out by selecting the surrounding cities of Shanghai as the contrast data source, and the spatial correlation of aerosol concentration in Shanghai will be expounded in combination with the inversion value.
