Minimize Sensor Performance, Products and Algorithms

The  Sensor Performance, Products and Algorithms (SPPA) is the element of the ESA Earth Observation ground segment responsible and performing the following activities:

(R) Alfred Wegener InstituteCourtesy of Alfred Wegener Institute 

Algorithm Development

Developing and upgrading the data processing algorithms in order to meet mission requirements and user needs.

Cal/Val 

Calibrating the sensors (through the update of on-board and on-ground configuration data) in order to meet product quality requirements.

Validating the generated products assessing, by independent means, the  quality  of  the  generated EO data  products.

Routine Quality Control

Monitoring routinely the status of the  spacecraft  (payload  and  platform) and  to check if the derived products meet the quality requirements along mission life-time.

The activities related to the SPPA constitute a long and continuous process involving a number of various actors with different competencies and objectives.

SMOS level 2 sea surface salinity products v662 released to users

16 May 2017

ESA would like to inform that SMOS level 2 sea surface salinity products version v662 are now available to the users.

The main changes introduced in the user product v662 are:

  • the replacement of sea surface salinity 1 field with the retrieved sea surface salinity based on an updated single roughness model and corrected for land-sea contamination effect
  • the replacement of sea surface salinity 2 field with the retrieved sea surface salinity based on an updated single roughness model
  • the replacement of sea surface salinity 3 field with the sea surface salinity anomaly (corrected for land-sea contamination) based on World Ocean Atlas climatology (WOA-2009)
