DTI wind speed database

Previously the DTI published a database of average wind speeds at 10, 25 and 45 metres above ground level for every square kilometre of the UK. The project was discontinued and the website archived, some of the links are now broken. At the time the data files were freely available and as a public service Fluke is making these files available now:

Original ASC files

Original ASC files plus DTI software

Although the data files have a *.asc extension they are NOT ESRI compliant rather they are simply readable plain text 'ascii' files. Fluke carried out some original work to convert the data files from the proprietary DTI format to ESRI-compliant ASC files which should be suitable for GIS software (they have been successfully tested with Autodesk AutoCAD Map 3D 2019

10 metres above ground level wind speed

25 metres above ground level wind speed

45 metres above ground level wind speed

For readers without GIS software interested in viewing the data, Fluke has produced a three page pdf showing a map of the UK colour-coded according to wind speed

Index: Page 1 = 10m AGL; Page 2 = 25m AGL; Page 3 = 45m AGL

Key: 1-3 m/s = dark grey; 3-6 m/s dull red; 6-7 m/s red; 7+ m/s yellow
