Dominant Wave Period
Measurement Instruments
Measurement Definition: One feature of the ocean wave spectrum. It is the period of the most energetic wave in the spectrum - Physical unit: [ s ] - Accuracy unit: [ s ].
| Instrument | Status/
Accuracy | Instrument Description | Measurement Technology | Timeline |
| 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. | Imaging radar (SAR) |  |
| SWIM | Operational | Ku-band Real-aperture radar (RAR) system, multi-incindence beams(0-10°) and azimuth scanning. Measurement of 2D ocean waves spectrum | 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. | Imaging radar (SAR) | |
