Ocean Surface Currents (Vector)
Measurement Instruments
Measurement Definition: Water flow on ocean surface - Physical unit: [ cm/s ] - Accuracy unit: [ cm/s ] intended as vector error, i.e. the module of the vector difference between the observed vector and the true vector - Measuring Units cm/s, Uncertainty Units cm/s

| C-Band SAR | Operational | Marine core services, land monitoring and emergency services. Monitoring sea ice zones and arctic environment. Surveillance of marine environment, monitoring land surface motion risks, mapping of land surfaces (forest, water and soil, agriculture), mapping in support of humanitarian aid in crisis situations. | n/a |  |
| SAR (RADARSAT-2) | Operational | All-weather images of ocean, ice and land surfaces. Used for monitoring of coastal zones, polar ice, sea ice, sea state, geological features, vegetation and land surface processes. | n/a | |
| SAR (RCM) | Operational | All-weather, C-band data to support ecosystem monitoring, maritime surveillance and disaster management. | n/a | |
| SAR-L | Operational | Land, ocean, emergencies, soil moisture, interferometry, others. | n/a | |
| X-Band SAR | Operational | High resolution images for monitoring of land surface and coastal processes and for agricultural, geological and hydrological applications. | n/a | |
| L-band SAR | Being developed | L-band SAR instrument offering full polarimetry, high spatial resolution, high sensitivity, low ambiguity ratios and capability for repeat-pass & single-pass cross-track interferometry to measure surface deformation of vegetated terrain, soil moisture, land cover classification, crop type discrimination and its temporal analysis. Furthermore, it will monitor Polar ice sheets and ice caps, and the sea-ice conditions (i.e. type, drift, deformation, concentration, lead fraction), as well as contribute to the European maritime situational awareness. | n/a | |
| L-Band SAR | Proposed | Global observation of dynamic processes in the bio-, cryo-, geo- and hydrosphere. | n/a | |
