Envisat Wind and Wave Products: Monitoring, Validation and Assimilation
نویسندگان
چکیده
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 inverted ASAR Wave Mode Level 1b product agrees well with the wave model counterpart while Level 2 product agrees well with the wave model in terms of swell wave height and mean period only. RA-2 Ku-band SWH and ASAR Wave Mode Level 1b products are assimilated in the ECMWF operational wave model. The assimilation has positive impact on model analysis and forecast.

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...
متن کامل4D-VAR chemical data assimilation of ENVISAT chemical products (BASCOE): validation support issues
RESUME A 4D-VAR chemical data assimilation system, BASCOE, is used to assimilate the chemical observations taken by the three dedicated instruments onboard Envisat. For the first time data assimilation takes active part in the validation of chemical atmospheric observations. Here we present the results of the assimilation of MIPAS NLE products and NRT products. It is shown that the MIPAS constr...
متن کاملValidation of a Regional Wave Model with Envisat and Buoy Observations
A high resolution North Atlantic and European Wave (NAEW) model has been developed in the Met Office. It is framed in a rotated latitude-longitude grid with a space resolution of 12 km and based on the same physics as the Met Office global wave model except for a new 3 order positive-definite advection scheme and a new Sub-Range Wave Height (SRWH) output variable. The wind forcing comes from a ...
متن کاملAssimilation of Ers and Envisat Wave Data at Ecmwf
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. ...
