NH Validation results for merged / multi-sensor product
In the following table, monthly validation statistics for the multi-sensor/merged sea ice drift product are reported upon. X and Y denote the 2 components of the drift vectors. b() is the bias and s() the standard deviation of the error e(X) = Xproduct - Xreference (in km). Columns 6, 7 and 8 are respectively the slope, the intercept of the regression line, and the Pearson correlation coefficient between Product and Reference data pairs. N is the number of collocation data pairs.

Validation dataset
Drifting stations
Validation is performed by collocation of the drift vectors with the trajectories of in situ drifters. Those drifting objects are generally buoys (e.g. the Ice Tethered Profilers) or ice camps (e.g. the Russian manned stations) that report their position at typically hourly intervals. Those trajectories are generally made available in near-real-time or at the end of the mission onto the ice.
Position records are acquired either via the GPS (e.g. those of the ITPs) or the Argos Doppler-shift system (those of the iABP). GPS positions are very accurate (accuracy better than 50 m) while those obtained by Argos have worse accuracy (approximately 350 m for 'high quality' records).
SAR-based motion vectors
The ice drift product processed from Envisat ASAR WSM scenes at the Danish Technological Institute (DTU) and available via the MyOcean project have been used as validation data for the OSI SAF low resolution ice drit products (mainly for SH).
Vectors originally spanning 24-hours are concatenated to producte 2-days displacements that are collocated with the OSI-405 ice drift vectors.
Collocation strategy
A nearest-neighbor approach is used for the collocation, and a collocation pair enters the validation dataset if and only if:
- The distance between the satellite product and the buoy is less than 30 km; and
- the mismatch of start time of the drift is less than 3 hours; and
- the mismatch of drift duration is less than 3 hours.
In the case when several validation vectors are collocated to a unique OSI-405 ice drift vector, only one is kept for the validation, preferably GPS-based vectors, then SAR-based, then Argos-based. The matchup database is futher thinned so that all data pairs are at least 2 * 62.5 = 125 km apart.
