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 | Approved | L-band SAR instrument combining wide swath, high spatial resolution, high sensitivity, low ambiguity ratios, full polarimetric acquisition capability, and repeat-pass interferometry to support the retrieval of surface deformation over vegetated terrain, above-ground biomass density, soil moisture, land cover and land-cover change, flooded area information, ice sheet and glacier velocity, snow water, sea-ice conditions (type, concentration and motion), ocean winds and sea state conditions, as well as enhancing European maritime situational awareness. | Imaging radar (SAR) | |
| NG C-Band SAR | Approved | 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) | |
