title: [Study on influencing factors and universality of chlorophyll-a retrieval model in inland water body].
abstract: The semi-analytical three-and four-band model and bio-optical analytical model of chlorophyll-a were checked by the 'mh, constituents and optical properties with high spatio-temporal variation. The influencing factors and universality of the retrieval model were studied by the modeling checking results. The study results indicate that the unjversality of bio-optical analytical model is much higher than the three-and four-band model, and the accuracy of the retrieval model is acceptable, but the accuracy of the retrieval model was highly affected by the specific absorption coefficient of chlorophyll-a. The accuracy of the three-and four-band model higher than the bio-optical analytical model. However, the universality of the three-and four-band model is not very high, because of the optimal wavelength position of the retrieval factors and the greater variability of the retrieval model parameters. The spectral shape of particle backscattering coefficient and chlorophyll-a specific absorption coefficient are the dominant influencing factors of the three and four-band retrieval model.
