Type of dataset: Sentinel-6 Skewness Products (S6_L2P_Skewness)

Digital Object Identifiers (DOIs):  10.24400/527896/A01-2024.012 - more metadata

Condition of access: This product is distributed by AVISO under standard AVISO+ license agreement.

Contents: This product provides skewness parameter and swh and sigma0 parameters.. The dataset includes measurements from Sentinel-6 in High and Low resolutions.

Use: 

Description: The Sentinel-6 Level-2P skewness products was developed to estimate the skewness from Sentinel-6 LR and HR acquisitions. That demonstration product is generated by different retracking processes, provides an initial estimation of such a phenomenon and allows a finer description of the sea state.

Geographic coverage: global.
