X-TRACK-L2P: Sea Level Anomalies dedicated to coastal applications (2022 version)
Types of dataset: Altimeter Sea Level Anomalies dedicated to coastal applications at 1Hz
DOI: 10.24400/527896/a01-2022.020 - more metadata
Contents: Along-track Sea Level Anomalies projected onto the reference tracks with a spatial interval of about 6-7 km between points (1 second). The Sea Level Anomaly time series have been computed with the X-TRACK processing system (developed at LEGOS) starting from the Level 2 Plus (L2P) products distributed by Aviso+. The altimetry corrections applied are those provided in this product. See the details of the L2P processing on the dedicated product page.
Use: coastal applications
Description: multimission altimeter satellite product in delayed time

Tools:
- User handbook
- Example of python script to read the files and plot several types of figures
