Abstract In order to build a more reasonable and accurate remote retrieval model than the models used before, the authors measured water spectral reflectance by field spectrometer in sea area of Hebei Province. Based on analyzing the relationship between spectral reflectance and actual measured value of chlorophyll-a concentration, the authors conducted correlation analysis between the reflectance of each band or band combination of MODIS data and measured value of chlorophyll-a concentration. The result shows that the best inversion band is B1. Then the remote sensing monitoring model of chlorophyll-a concentration was built by using B1 of MODIS data. The retrieval results and corresponding actual measured results were compared with each other at last. The results show that the correlation coefficient of this model is 0.66 and the root mean square error of inversion result is 0.48 mg/m3. The precision of this retrieval model is better than OC3 standard empirical algorithm of SeaDAS. Therefore, the model could be employed to retrieve chlorophyll-a concentration of surface water of Hebei sea area effectively by using MODIS data.
