AbstractMonitoring the dynamic characteristics of the diffuse attenuation coefficient (K-d(490)) on the basis of the high temporal-resolution satellite data is critical for regulating the ecological environment of lake. By measuring the in-situ K-d(490) and the remote-sensing reflectance, a semi-analytical algorithm for K-d(490) was developed to determine the short-term variation of K-d(490). From 2006 to 2014, the data about 412 samples (among which 60 were used as match-up points, 282 for calibrating dataset and the remaining 70 for validating dataset) were gathered from nine expeditions to calibrate and validate the aforesaid semi-analytical algorithm. The root mean square percentage error (RMSP) and the mean absolute relative error (MAPE) of validation datasets were respectively 27.44% and 22.60 +/- 15.57%, while that of the match-up datasets were respectively 34.29% and 27.57 +/- 20.56%. These percentages indicate that the semi-analytical algorithm and Geostationary Ocean Color Imager (GOCI) data are applicable to obtain the short-term variation of K-d(490) in the turbid shallow inland waters. The short-term GOCI-observed K-d(490) shows a significant seasonal and spatial variation and a similar distribution to the matching Moderate Resolution Imaging Spectroradiometer (MODIS) which derived K-d(490). A comparative analysis on wind (observed by buoys) and GOCI-derived K-d(490) suggests that wind is a primary driving factor of K-d(490) variation, but the lacustrine morphometry affects the wind force that is contributing to K-d(490) variation.
