Time series of validation results for sea ice
Results below are for the daily average for the 4th day after the day when the bulletin was issued. The bulletin date is given as the x-axis coordinate in the images below. Average values for the time series that are displayed, are given in parenthesis in the line label legend.
The observational product for sea ice concentration/ice edge position of type ice charts is only available for working days. Hence, data are missing for forecast days that correspond to Saturdays and Sundays.
