Assimilation of Ers and Envisat Wave Data at Ecmwf
نویسندگان
چکیده
Operational wave data assimilation at ECMWF started with ERS-1 radar altimeter wave heights on 15 August 1993. This had a significant impact on the wave model analysis and forecast. The impact of wave data assimilation based on the ECMWF experience is presented. This includes the impact of assimilation of ERS radar altimeter and synthetic aperture radar and ENVISAT radar altimeter-2 wave data. The impact of assimilation on both model analysis and forecast is verified against data from wave model analysis, in-situ (wave buoy) observations, satellite observations and a combination of all of these sources (multiple-collocation). The impact of simultaneous assimilation of several data sources is presented and discussed as well.

Envisat Wind and Wave Products: Monitoring, Validation and Assimilation
ENVISAT fast delivery RA-2 and ASAR wind and wave products are routinely received, monitored and validated at ECMWF. RA-2 wind speed product is of good quality. Although Ku-band significant wave height (SWH) product is slightly high, it is of high quality. The redundant side B of RA-2 produced SWH product of even better quality. The S-band wave height product is generally of good quality. The i...
متن کاملGlobal wind speed retrieval from SAR
The global availability of synthetic aperture radar (SAR) wave mode data from the European Remote Sensing (ERS) satellites ERS-1 and ERS-2, as well as ENVISAT, allows for the investigation of the wind field over the ocean on a global and continuous basis. For this purpose, 27 days of ERS-2 SAR wave mode data were processed, representing a total of 34 310 imagettes of size 10 km 5 km, available ...
متن کاملLong Term Assessment of Ers-1 and Ers-2 Wind and Wave Products
The wind and wave products from the ERS mission provide an invaluable data set. This paper provides an overview of the performance of both ERS-1 and ERS-2 products on the basis of surface winds from the consistent ECMWF 40-Year Reanalysis (ERA-40), and wave fields from a long term stand-alone wave model hindcast run forced by ERA-40 winds. Furthermore, buoy and other in-situ measurements are us...
متن کاملRe-introduction of Ers-2 Scatterometer Data in the Operational Ecmwfassimilation System
At the European Centre for Medium-Range Weather Forecasts (ECMWF), scatterometer data from the ERS 1/2 platforms have been successfully assimilated between January 1996 up to an ERS-2 on-board failure in January 2001. This surface vector wind product over the global oceans had proven to give a positive impact on the ECMWF forecast skill in general, and the analysis of tropical cyclones in speci...
متن کاملGlobal wave model validation using ENVISAT ASAR wave mode data
Spaceborne active radar remote sensing, e.g., radar altimeter (RA) and synthetic aperture radar (SAR) have been playing an important role in the validation of numerical wave models, particularly in open ocean. Most forecast centres also use altimeter data in the wave data assimilation process. In this paper we present validation results based on the newly developed CWAVE_ENV algorithm. SAR wave...
