Sentinel-3A mission was successfully launched in February 2016. It is a multi-instrument mission to measure surface topography, sea- and land-surface temperature, ocean colour and land colour with high-end accuracy and reliability. We focus here on the observations acquired over ocean by the surface topography payload that encompasses a dual frequency altimeter, a dual frequency radiometer and Doris and GNSS sensors.

ESA and EUMETSAT have defined the Mission Performance Framework for qualifying the performance of the Sentinel-3 mission, sensors and products. One important piece of this component is the Mission Performance Centre, which is in charge of the performance of the Optical Mission and of the Surface Topography Mission (STM).

The Sentinel-3 Mission Performance Centre (S3-MPC) has been charged with different main activities for the STM:
• Quality Control activities
• The calibration, characterisation and performance of the altimeter (SRAL) and the microwave radiometer (MWR) sensors
• Validation of the products and ground processing
• Assessment of the mission performance
• Support for the continuous improvement of the S-3 STM performance

The present paper will detail the results on the STM Sentinel-3A Level 2 product quality and on the mission performance. Based on the first months of Sentinel-3A data, this assessment done by the MPC and EUMETSAT will address the performance obtained over ocean and coastal areas for different parameters (topography, wind and wave). The mission performance will be measured through the comparison to other altimeters and models. A focus will be done on the quality of the SARM data that are available for the first time at global scale.
