- Abstract
Sea-ice concentrations retrieved from satellite microwave radiometry data are influenced by many natural factors. In the work we consider sea-ice contamination. The values of sea-ice concentration derived with the use of the ASI, TUD, OSI-401-b, BT, NT, and CDR algorithms are analyzed on the example of fast ice in the East Siberian Sea. These algorithms are chosen because they are available for open access and are commonly used in scientific research. All of the algorithms return lower ice concentrations in contaminated ice as compared to clean ice during the active ice-melt period, from late May to early July. The ASI and TUD are the two most sensitive to sea-ice contamination, which is due to the high-frequency channels, 85–91 GHz, used in them.
