An operational chlorophyll-a retrieval algorithm by remote sensing in Hebei coastal sea
摘要
Abstract
An operational remote sensing retrieval model of chlorophyll-a concentration in Hebei coastal sea was established.A correlation analysis was calculated between the reflectance of MODIS 1B band 1 and actual-measured value of chlorophyll-a concentration,and an inversion model of remote sensing was established by regression.The modeled data was compared with the observed chlorophyll-a concentration in different time and regions to verify the accuracy and stability of the model.The results showed that the correlation coefficient between the modeled data and observed data was 0.73,and the average relative error was between 31.4% and 35.9%.The model can be effectively applied to retrieve chlorophyll-a concentration of surface water in Hebei coastal sea by using MODIS data.It has great realistic significance on red tide and eutrophication monitoring in Hebei coastal sea.关键词
