Upper air Tab

Dear WAsP team,

Maybe this has a very obvious answer but, what is the meaning of "upper air tab" available in new version of WAsP and how do we use it ?

Thanks,
Ricardo

The 'upper-air tab' is an old option that has been reactivated in the latest version of WAsP 10. It describes the statistics of the geostrophic wind and is the observed wind climate that can be obtained from analysis of radiosonde observations. This wind climate is not influenced by the details of the terrain surface in the same way as mast observations, and the data must be treated accordingly. The European Wind Atlas contains a number of upper-air stations lke this.


When using an upper-air observed wind climate, the measurements height is specified as a non-numeric value such as '*'.
