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. |
ERS-1 Scatterometer L2 dataset available online
13 June 2019
The reprocessing campaign for the ERS-1 Scatterometer Level 2 products has been completed. The ERS Scatterometer Level 2 dataset now comprises a continuous series of back-scattering measurements, Ocean Winds and Sea Ice probability from August 1991 to July 2011. The reprocessed dataset is now accessible to users together with the corresponding ERS-2 data on the ESA dissemination server and is provided through ESA fast registration.
