Quasi-simultaneous measurements of the ocean surface by the Canada Centre for Remote Sensing (CCRS) Convair-580 (CV-580) synthetic aperture radar (SAR) were acquired on March 20, 1988, along an ascending pass of the Geosat radar altimeter as part of the prelaunch ERS-1 Norwegian Continental Shelf Experiment (NORCSEX '88). Over a region where the SAR look direction is parallel to the wind vector...

Given the advances in online data acquisition systems, statistical learning models are increasingly used to forecast wind speed. In electricity markets, farm production forecasts needed for day-ahead, intra-day, and real-time markets. this work, we use a spatiotemporal model that leverages dynamics Using priori knowledge of direction, propose maximum likelihood estimate inverse covariance matri...

In this paper it is shown a process to demarcate areas with analogous wind conditions. For this purpose a dispersion graph between wind directions will be traced for all stations placed in the studied zone. These distributions will be compared among themselves using the hierarchical clustering algorithm. This information will be used to build a matrix, letting us work with all relations simulta...

Fossil Fuels are always considered as environmental pollutants. On the other hand, the political and economic situations highly affect the price of these fuels. Offshore wind and wave, as renewable energy sources, represent the better alternatives for electricity generation. Therefore, it is necessary that wind speeds effectively be estimated due to the absence of field measurements of the wind...

Observations from several towers are used to show how measurements of wind arid.temperature near the surface can be used to estimate the variances of the horizontal velocity and the dissipation rate up to the top of the towers, provided the roughness length is known. The roughness length usually varies with wind direction, and the traditional methods of estimating it tend to lead to overestimat...

Data of wind speed, wind direction and temperature obtained from a meteorological mast and a RASS sodar are contrasted. Wind data were compared at a height of 100 m and temperature at 51 and 100 m. 10 minute averages during the month of April 2001 were used. Wind speeds showed satisfactory correlation and the temperature fit was better at 100 m than at 51 m. Mast data were steadier than those f...
