Methods for wind field Computation from sparse observed wind data

Wind Field Models and Model Order Selection for Wind Estimation

A bstract-Traditional scatterometer wind estimation inverts the model function relationship between the wind and backscatter a t each resolution element, yielding a set of ambiguities due to the many-to-one mapping of the model function. Field-wise wind estimation dramatically reduces the number of ambiguities by estimating the wind for many resolution elements, simultaneously, using a wind fie...

Wind field retrieval from SAR compared with scatterometer wind field during ERS Tandem phase

Several recent works [such as Vachon et al. 1996, Scoon et al. 1996 and Korsbakken et al. 1997] report promising results when wind retrieval models developed for the wind scatterometer (WSC) are applied to SAR data. The general conclusion from these works is that more validation is needed since the available in-situ material is relatively limited. A dataset from the ERS-1/2 Tandem phase allows ...

Measurement and Data Analysis Methods for Field- Scale Wind Erosion Studies and Model Validation

Accurate and reliable methods of measuring windblown sediment are needed to confirm, validate, and improve erosion models, assess the intensity of aeolian processes and related damage, determine the source of pollutants, and for other applications. This paper outlines important principles to consider in conducting field-scale wind erosion studies and proposes strategies of field data collection...

A robust engineering approach for wind turbine blade profile aeroelastic computation

Wind turbines are important devices that extract clean energy from wind flow. The efficiency of wind turbines should be examined under various working conditions in order to estimate off-design performance. Numerous aerodynamic and structural research works have been carried out to compute aeroelastic effects on wind turbines. Most of them suffer from either the simplicity of the modelling appr...
