The altimetry processing chain – Bathymetry for BASE-platform

The present article describes some of the most relevant features of the designed calculation chain for bathymetric products from satellite altimetry method that has been integrated into the BASE-platform service. We estimate bathymetry based on up-to-date data from Cryosat2 where the new generation of altimetry radar (SAR mode) is processed in-house by using analytical solutions for the retracking model. A new method is used for the de-noising of residual altimetry profiles. The solutions are calibrated with in-situ soundings to consider seafloor density variations.
