Crossover Statistics and Trends

This section provides r.m.s elevation residuals in different modes and areas from the crossovers generated from 30 or 60-day datatakes of L2 GDR-A.

The first crossover data take starts from 18/10/2010, following the switch to SIRAL-A at the end of the commissioning phase.
