Please note: The data can be downloaded for free in parts. Wind multipliers are factors that transform regional wind speeds to local wind speeds considering local effects of direction, terrain, shielding and topographic influences. In order to assess the local wind hazard (spatial significance in the order 10's of metres), wind multipliers need to be computed, so that the regional wind speeds (order 10 to 100's of kilometres) can be factored to provide local wind speeds. This data package includes terrain, shielding and topographic multipliers for national coverage. It is based on tiles with dimension about 1 by 1 decimal degree in netCDF format. Each multiplier further contains 8 directions. The version 2 dataset was produced using the wind multiplier computation software 2.0. See Geocat 82481.
