SAR wave mode provides two-dimensional spectra of ocean surface waves. For this function the SAR records regularly spaced samples within the image swath. The images are transformed into directional spectra providing information about wavelength and direction of wave systems. Automatic measurements of dominant wavelengths and directions will improve sea forecast models, but the imagettes can also show the effects of other phenomena, such as internal waves, slicks, small scale variations in wind and modulations due to surface currents and the presence of sea ice.

Due to a planned software maintenance on Tuesday 30 October 2018, the ERS and Envisat (A)SAR On The Fly (OTF) dissemination service will be unavailable from 09:00 to 12:00 CET.
Furthermore, the maintenance activities may impact the OTF data search on the same platform (ERS and Envisat) from 13:00 to 15:00 CET.
