Dear Leen

Most weather data quotes the reference wind speed which is that at 10m above the ground as measured at certain weather stations. Adjustment factors are then made for levels of surface roughness, I.e. urban, rural environments. I think the TMY follows the same convention.

can anyone tell me what wind speed is exactly meant in the TMY. Is it the
free, undisturbed wind speed, the wind speed above the roof, the wind speed
at 10 metres above the ground ....
