The Sentinel-3A is the most recent altimetric mission of a long historical series.
It is well known the crucial importance of the instrumental calibration when processing the altimeter data , in order to produce reliable and accurate L2 geophysical retrievals, such as sea surface height, significant wave height, or wind speed over the oceans.
isardSAT, as Expert Support Laboratory within the Sentinel-3A Mission Performance Centre team, is responsible for monitor the calibration parameters during the Sentinel-3A mission.
This talk will present the first cycles of Calibration Monitoring data acquired during the Commissioning Phase of the Sentinel-3A SRAL instrument in all calibration modes, along with a comparison with the on-ground reference values.
