Short summary

I evaluated a novel sea-ice concentration data product based on satellite microwave observations during December 1972 to May 1977. I used Landsat-1 satellite images obtained in 1974 in the Arctic, classified into water and ice. My evaluation provides results very similar to evaluations carried out for sea-ice concentration data products based on more recent satellite observations. I suggest that the novel sea-ice concentration data product is a useful extension back in time.
