Wind mapping of the Canary Islands (2016)

Cartography promoted by the Ministry of Ecological Transition, Fight against Climate Change and Territorial Planning commissioned by the Technological Institute of the Canary Islands (ITC). The modeling and results generation was developed by AWS Truepower, SLU in 2015.

Wind mapping consists of four maps per island at heights of 40, 60, 80 and 100 meters, developed from a mesoscale weather model MASS (Mesoscale Atmospheric Simulation System), with a spatial resolution of 50x50 meters.

The structure of shapefile files includes the following fields:

• X. x-coordinate (EPSG:32628). Unit:m.
• Y. Coordinate and (EPSG:32628). Unit:m.
• SPDXX. Average annual speed at height XX (40, 60, 80, 100). Unit: m/s (x1E-2).
• POWERDEN. Wind power density. Unit: W/m2 (x1E-2).
• WEIBA. Weibull distribution scale factor. Unit: m/s (x1E-2).
• WEIBK. Weibull distribution form factor. Unit: (x1E-2).
• FRECNN. Frequency of the sector NN (01-16). Unit: % (x1E-1).
• WEIBANN. Scale factor of the Weibull distribution in the NN sector. Unit: m/s (x1E-2).
• WEIBKNN. Form factor of the Weibull distribution in the NN sector. Unit: (x1E-2).

The 16 sectors make up a north-facing wind rose. Each sector covers 22.5o and the first of them covers the arc from 348.75o to 11.25o.
