Monthly sea ice coverage derived from passive microwave satellite measurements. Ice extent is defined as the area bounded by the 15% ice concentration contour which is determined by summing up all the pixel areas (nominally 25km by 25km) which have concentrations greater than 15%. Sea-ice extent refers to the total surface area inside the ice-edge. This area inside the ice-edge is not necessarily covered by 100%.
