چکیده

As the goals for altimetric measurements become ever more precise, there is concern about the reliable detection and discarding of rain contaminated data. A dual-frequency rain detection technique developed for the Kuand C-band TOPEX altimeter, is adapted for the Kuand S-band RA-2 altimeter on Envisat. Of particular concern is the selection of a suitable threshold to minimise the quantity of good data inadvertently

Rain and Ice Flagging of Envisat Altimeter and Mwr Data

Altimetry range, wave height, and wind speed measurements are often corrupted by two effects over the ocean: rain and sea-ice. Radiometer measurements, which provide the altimetric wet troposphere correction, are similarly corrupted by the presence of rain or sea-ice in the instrument's footprint. To avoid contamination of sea surface height measurements, it is imperative that data influenced b...

Analysis of the Effect of Rain on the Envisat Altimeter: Definition of a Rain Flag

Past experiences with ERS and Topex/Poseidon altimeter data have shown that rain can significantly alter the quality of altimeter measurements (dynamic heights, significant wave heights, wind speed) [1][2][3][4]. Among all the different atmospheric phenomena which can affect the altimeter measurement, rain is one of the less well understood and at present no reliable correction can be made for ...

Ku-band Radar Altimeter Surface Wind Speed Algorithm

An algorithm for the retrieval of surface wind speed from Ku-band altimeter backscatter coefficient is proposed. The algorithm was derived using two-month worth of ENVISAT altimeter backscatter data collocated with ECMWF model and buoy wind speeds. The algorithm was extensively verified for ENVISAT, ERS2 and Jason-1 altimeters. The algorithm performance is better than the “modified Chelton-Went...

Comparison of the Envisat Waveform Retrackers over Inland Waters

Since the launch of ENVISAT satellite in 2002, the Radar Altimetry Mission provides systematic altimeter observations of the Earth surface. The ENVISAT Geophysical Data Records products contain, over all type of surfaces, altimeter ranges derived from four specialized retrackers: Ocean, Ice-1, Ice-2 and Sea-Ice retracker. Among the different goals of the ENVISAT Mission, one directly concerns l...

Envisat Ocean Altimetry Performance Assessment and Cross-calibration

Nearly three years of Envisat altimetric observations over ocean are available in Geophysical Data Record (GDR) products. The quality assessment of these data is routinely performed at the CLS Space Oceanography Division in the frame of the CNES Segment Sol Altimétrie et Orbitographie (SSALTO) and ESA French Processing and Archiving Center (F-PAC) activities. This paper presents the main result...
