**3. Qualitative assessment**

This section investigates the quantity of retracked SLAs from the three retrackers (i.e., MLE-4, Ice-1, and Ice-2) that are available from the AVISO SGDR product. The quantity is computed in terms of the percentage of data availability over the region (Section 3.1) and the minimum distance to the coastline (Section 3.2). These assessments are conducted to evaluate the amount of data that can be recovered through those three retracking algorithms.
