Data sets

Gridded Sea Level Heights - Arctic Ocean (https://www.aviso.altimetry.fr/) P. Prandi https://doi.org/10.24400/527896/a01-2020.001

Sea level measured by tide gauges from global oceans as part of the Joint Archive for Sea Level (JASL) since 1846 (http://uhslc.soest.hawaii.edu/data/) P. C. Caldwell, M. A. Merrifield, and P. R. Thompson https://doi.org/10.7289/V5V40S7W

Short summary

We investigate how mapping sea level in the Arctic Ocean can benefit from combining data from three satellite radar altimeters: CryoSat-2, Sentinel-3A and SARAL/AltiKa. A dedicated processing for SARAL/AltiKa provides a baseline for the cross-referencing of CryoSat-2 and Sentinel-3A before mapping. We show that by combining measurements coming from three missions, we are able to increase the resolution of gridded sea level fields in the ice-covered Arctic Ocean.
