Bio-optical retrieval model of suspended particle in Tai Lake using MERIS image
太湖水体悬浮颗粒物生物光学模型及MERIS数据反演

The single infrared wavelength bio-optical retrieval model of suspended particle matter concentration (Cmin) based on the bio-optical properties of suspended particle matter in Taihu Lake has specific mechanism. The measured data of suspended particle matter and bio-optical properties during 2006 to 2009 were used to test this bio-optical algorithm. The results indicate that: the spatio-temporal variation of specific backscattering coefficient is the primary influencing factor to the retrieval precision of suspended particle matter. The absorption coefficient of suspended particle matter in the infrared wavelength also have significant effect on the retrieval precision of suspended particle matter. This retrieval model can be successfully apply to the MERIS image data. The resuspended sediment will significantly increase the concentration of suspended particle matter in Taihu Lake according to the MERIS image retrieval result and wind speed monitor data in situ.
