  1. Hi Rogier, thanks for your answer. In fact, I have two time series, each one corresponding to a different measurement height (60 m and 100 m) in the same met mast, that is to say, I have two anemometers. So, in order to get a comparison between the GWC associated to each one of those anemometers, I used WAsP to calculate the AEP for the same wind farm twice, with the GWC generated. The analysis showed that there are remarkable differences whenever I change the GWC, even if they correspond to the same met mast, but at different heights. My question is: is that difference due to any vertical extrapolation model limitation? If it's not clear yet, please let me know. Thank you once again!
  2. Hi, This may not be a very reasonable question, but I have a doubt concerning the difference between the generalised wind climate calculated from two hub heights with the same time series. I did it in my project for measured data at 60 m and 100 m height for a wind turbine with a hub height of 70 m, and I was expecting them to provide the same GWC, which did not occured. That led the wind farm capacity factor of each one to have a difference of almost 4%. I would like to know if there is any obvious explanation for this, and if there is anything I can do to compensate for that discrepancy when calculating my wind farm AEP. Thanks!
  3. Thank you for your answer, Andreas.
  4. Hi, I've inserted an obstacle group while setting the met. mast for my analysis, and now I want to generate a resource grid. Do I have to reassociate the same obstacle group to the new resource grid or, if I just let things as they are, WAsP will automatically associate the original obstacle group to the resource grid? Thanks.
