Merged Altimeter Wave Height Product

A merged altimeter wave height data base has been set up by Ifremer, providing wave height, backscatter coefficient and wind speed.

 The Ifremer Laboratoire d'Oc√©anographie Spatiale (LOS) is involved in several aspects of the GlobWave project. Besides these Globwave dedicated activities an independent monitoring of the quality of significant wave height, and wind speed, measurements from the altimeters was performed regularly for a long time.

A merged altimeter wave height database has been set up, providing GDR Ku-band wave height, backscatter coefficient and wind speed, together with proposed corrections.

Update December 2011: the merged altimeter merged database has been improved, with new information including C-band backscatter coefficient and 1 Hz standard deviation values for the Jason-1 & Jason-2 datasets, S-band backscatter coefficient and 1 Hz standard deviation values for ENVISAT, new SWH calibrations applied to ERS-2, Jason-1 & Jason-2 datasets, new data screening for ENVISAT, Jason-1 & Jason-2 and the ENVISAT GDR dataset reprocessed in version V2.1.

Documentation describing in full the database improvements can be found on the Ifremer ftp site: ftp://ftp.ifremer.fr/ifremer/cersat/products/swath/altimeters/waves/documentation.

The merged altimeter database is available on the Ifremer ftp site: ftp://ftp.ifremer.fr/ifremer/cersat/products/swath/altimeters/waves/data.
