Inversion of Sea Ice Concentration in the Liaodong Bay from MODIS Data

Sea ice concentration is an important observation element and a necessary input parameter for the numerical prediction of sea ice. In this study, new method developed inversion (SIC) in Liaodong Bay from MODIS data based on Normalized Difference Water Index (NDWI). By comparing inverted results NDWI WU’s methods, as well observations six shore-based points east coast winter 2016/2017 Landsat 8 OLI data, shown to be useful tool estimate SIC. The SIC obtained by good agreement with survey data. mean absolute error between visual about 10%. comparison 92% values are less than 20%. average value 1%, that −10%, which means accuracy better. deviation 9% 13%, shows certain improvement precision. validation show precision better method, consistent result
