Altimetry product innovative coastal approach (ALTICAP)

Altimeter Sea Level Anomalies dedicated to coastal applications containing Experimental Jason-3 altimeter 20Hz along-track satellite coastal product in delayed time and global (from 0 to 500 km from the coast). This product has been developed with the goal of providing simple and easy-to-use files with a resolution consistent with the observable physical signal. The given Sea Level Anomaly (SLA) has been corrected with standard corrections. Those corrections are provided in the files so that users can apply their own correction. Some fields from the level 2 product (L2) such as altimetric wind speed and significant wave height are also provided to facilitate certain applications. Two types of datasets are distributed: 1/a dataset of one file per day containing one day of measurements for several tracks, and 2/ a dataset of one file per track containing the time series over the whole period.
