Additional information

It is assumed to be entirely ice covered with at least 15 % concentration. However, the 'area' column excludes the area not imaged by the sensor. This area is 1.19 million km2 for SMMR (35) (from the beginning of the series through June 1987) and 0.31 million square kilometres for SSM/I (36) (from July 1987 to present). Therefore, there is a discontinuity in the 'area' data values in this file at the June/July1987 boundary.
