Experimental Products: Polar Ocean Along-track Level-3 Sea Surface Heights
Experimental along-track level-3 product of Sea Surface height Anomalies from 50°N up to 88°N for the Arctic Ocean and 50°S to 88°S for the Southern Ocean. The products include ice-covered regions using sea level observations within the leads (open water area within a fracture of sea ice). Waveform classification of satellite echoes is performed to differentiate leads and open ocean from floes measurements using neural-network-based classification method. Then the missions are cross calibrated on SARAL/AltiKa and the Sea Level Anomalies along-track data from 3 altimetry missions are generated. Therefore, the files available are the 3 along-track monomission files: SARAL/AltiKa, Cryosat-2 and Copernicus Sentinel-3A.
