Overall Mean


Based on data from January 1979 to December 1999. Contour of overall mean values from each model.

Overall Standard Deviation


Based on data from January 1979 to December 1999. Contour of overall standard deviation values from each model.

Monthly Mean


Based on data from January 1979 to December 1999. Contour of monthly mean values from each model.

Monthly Mean Standard Deviation


Based on data from January 1979 to December 1999. Contour of monthly standard deviation values from each model.

Histogram Field


Based on data from January 1979 through model time domain. Histograms of values for each month were stacked bottom to top and the height of the histogram for each parameter value at each month was contoured. Values on land are excluded from calculations.

H1: Contour histogram height, where the contour values represent the true height.
H2: Contour of histogram height, where the contour values represent the difference between the true height and the column-bin height.
H3: Contour of histogram height, where the contour values represent the difference between the true height and the monthly mean height.
H4: Contour of histogram height based on the anomalies, where anomalies are the differences between raw values and monthly mean values.

Time Series


Based on data from January 1979 through model time domain. Values on land were excluded from calculations.

Monthly Thickness: Time series of overall mean monthly thickness by region for each model. Based on all non-missing nodes.
Monthly Thickness Anomalies: Time series of overall mean monthly thickness anomalies by region for each model, where anomalies are the difference between raw values and monthly mean values. Based on all non-missing nodes..
Open Water Percentage: Time series of percentage of open water by region for each model. Based only on nodes which were active (e.g. non-missing) for all models.

Ensemble Differences


Based on data from January 1979 to December 1999. Contour of the difference between model and overall, April, and September model ensemble values, respectively.

Ensemble Mean: Difference is based on the model ensemble mean.
Ensemble Median: Difference is based on the model ensemble median.
Ensemble Standard Deviation: Difference is based on the model ensemble standard deviation.
