- Résumé
-
This data set contains radar observations of the ocean surface . The instrument is an airborne Ku-Band Doppler radar named "KuROS".
This instrument was designed to measure the directional spectra of surface ocean waves , the ocean surface wind vector, and related parameters including the normalized radar cross-section profile with incidence.
This data set is relative to the Level 1 product, which contains the radar wave form (intensity and phase) versus range (with 1.5m or 5 m resolution), the normalized radar cross-section versus incidence angle and ancillary data related to the geometry and localization of observations. The data cover two ranges of incidence angles (one between 5 and 20° from nadir and the other one around 40°) and all azimuth angles. Level 2 data will correspond to ocean wave spectra estimated from the observations collected between 5° and 20°.
This data set is relative to the 2015 masurement campaign with 5 flights over the Iroise sea (near to the Atlantic coast of Brittany-France) in October 2015.
- Méthode(s)
- The Leve 1 products are obtained from the raw data of KuROS after the following main steps: time integration over 33 ms, conversion to geophysical units, radiometric and geometric corrections to obtain the normalized radar cross-section. See Caudal et al, JAOT 2014 for more details.
- Informations techniques
-
The user is informed that for the data from the 2015 campaign, the full calibration of the radar is not guaranteed so that the normalized radar cross-section may need an additional global calibration.
The KuROS data can be downloaded with 3 possible choices:
1) original 30-s file by 30-s file (the filename gives the mode of radar acquisition, the date and the starting time of acquisition)
2) a compressed file (.zip) containing several 30-s files as selected by the user
3) one or several concatenated files, which group the files with data of a same type (same flight, same antenna, same flight level, same polarisation).
