ALES Jason-2 Coastal Altimetry Version 1
Adaptive Leading Edge Subwaveform (ALES) provides coastal and open ocean altimetric measurements by applying a specialized retracker to Jason-2 data. This is an along-track dataset that takes takes the high frequency SGDR data and retracks it to remove the waveforms that show land contamination. Therefore these data are provided at 20 Hz. It is similar to the Jason-2 SGDR data except that it also includes ALES variables for the range, significant wave height and sigma0 so that the user can calculate the retracked SSHA.
