The Sensor Performance, Products and Algorithms (SPPA) is the element of the ESA Earth Observation ground segment responsible and performing the following activities:
Courtesy of Alfred Wegener Institute
Developing and upgrading the data processing algorithms in order to meet mission requirements and user needs.
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.

Image quality issues have been detected on the ESA Landsat 8 TIRS products which systematically contaminate the Band 10 and Band 11 TIRS data, the OLI data remains unaffected. Discussions are ongoing with the view to reprocess the Landsat 8 data with the latest software and supporting data to recover the affected products. More information can be found at the Landsat 8 Product Anomalies webpage
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)

The third International Ocean Colour Science (IOCS) meeting will take place from 15 to 18 May 2017 in Lisbon, Portugal, followed by two training events on 19 May 2017: a Copernicus marine data stream training event and a SeaDAS training event. The meeting is being convened by the International Ocean Colour Coordinating Group (IOCCG) in partnership with, and thanks to sponsorship from, EUMETSAT, ESA, the European Commission and NASA. Deadline to submit poster abstracts is 1 April 2017.
The ESA workshop "Options for future European satellite OCR (Ocean Colour Radiometry) vicarious adjustment infrastructure for the Sentinel-3 OLCI and Sentinel-2 MSI series", organised by the FRM4SOC team (Fiducial Reference Measurements for Satellite Ocean Colour) was held at ESRIN, Frascati from 21 to 23 February 2017.

The Proba-V full-mission re-processing campaign has been completed,
On-line access for the current Collection (C0) will be discontinued by end February 2017.
The new Collection 1 (C1) data set includes significant quality improvements with respect to the previous data version Collection 0 (C0):
- Updated Cloud detection
- Re-fined radiometric calibration parameters
- Release of the intermediate L2a products
- Meta data compliancy to Climate and Forecasting conventions (v1.6)
14 December 2016
The re-processing campaign of Proba-V Collection 1 products is proceeding, adopting the latest processor. Data from October 2013 up to September 2015 are now available to the user community. The re-processing campaign is expected to be finished by January/February 2017. Since 5 December 2016, the new processor was adopted for the near-real time processing.
