Sea Surface Heights (SSH)

Sea Surface Heights (SSH) based on Multi-Mission Satellite Altimetry
Sea Surface Heights (SSH) based on Multi-Mission Satellite Altimetry

Sea Surface Heights (SSH) are provided along-track for all available satellite altimeter missions. All measurements are already corrected by the most actual geophysical corrections (e.g. tides and atmospheric delays). Moreover, as the data of all missions have been carefully harmonized and cross-calibrated in advance (following the approach of Bosch et al., 2014), it should be possible to merge and combine SSH of any mission in order to improve the spatial and temporal resolution.
