Figure 1 : Comparison of buoys and Merged drifts for 3 day-lag, winters 1999-2004. Colors are probability expressed in logarithm scale.

Figure 2 : Angle difference between Merged and buoys as a function of Merged drift for 3 day-lag, winters 1999-2004. Colors are probability expressed in logarithm scale.

Figure 3 : Comparison of buoys and AMSR-E drifts for 3 day-lag, winter 2002-2003. Colors are probability expressed in logarithm scale.

Figure 4 : Angle difference between AMSR-E and buoys as a function of AMSR-E drift for 3 day-lag, winter 2002-2003. Colors are probability expressed in logarithm scale.

Figure 5 : Arctic sea ice drift from the combination of SSM/I (h and v polarizations) and SeaWinds/QuikSCAT at three day-lag February 2nd-5th, 2005. Drift vectors less than one pixel are marked with a cross. In red : identical drift for the 3 products, in green : identical drift for two of the products, in blue : selection or validation of one product.

Figure 6 : Arctic sea ice drift from AMSR-E at 3 day-lag February 2nd-5th, 2005. Drift vectors less than one pixel are marked with a cross. In red : identical drift for horizontal & vertical polarizations, in blue : selection or validation of one polarization.

Figure 7 : Times series of drift data density for the 2002-2003 winter for AMSR-E and Merged at 2, 3 and 6 day-lags.
