1. Brief  description:

The sea-ice cover data in the CMA re-forecasts was incorrect in the ECMWF S2S database prior to 31st March 2016. CMA confirmed that there was a problem in their data processing procedure which main effect was to have sea-ice values equal to 0 or 1 instead of covering the range 0 to 1.

The correct data was replaced in the ECMWF S2S database on 31st March 2016.
