New method of the Arctic sea ice cover reconstruction on the basis of SSM/I data is introduced. The method is based on electrodynamical models of radiation properties of ice and snow. Models take into account physical parameters of ice and snow and do not require any tuning. Comparison of modelled ice concentration with direct shipboard observations collected in Arctic and Antarctic research institute and covering time interval 2004–2009 and with different algorithms is presented. Raw satellite data were taken from the database GLOBAL–RT DMSP program. These data are permanently updated and routinely processed in the department of Earth studies from space in the Institute of space studies RAS.
