The Sensor Performance, Products and Algorithms (SPPA) portal, launched on March 2015 and designed to increase awareness of Earth Observation (EO) data capabilities and performance status within the EO user community, retired last 27 April with the arrival of the new Earth Online website.

SPPA aimed at providing online data and information concerning the SPPA activities on EO mission performance and covered ESA EO Missions, Multi Sensor Time-series and Third Party Missions.

For many years SPPA website provided the necessary information to help technical and scientific users familiarise themselves with the EO data and use the data products.

With the launch of the new Earth Online website the SPPA website is now part of this new website and the information about the instruments has been merged with the relevant pages. The old and well-known SPPA website will be dismissed soon.
