  1. Thanks Mark and Morten for taking the time to reply. I have been able to download the document, and I think I will consider MCP on alpha for future projects, it looks very interesting. For this project, I ended up using an alpha from the mast measurements since seasonality was affecting lidar's alpha. Then, for verification, I compared the wind speed obtained at 120 m with the speed measured by lidar at 120 m for the same reference period. Thanks again, Kind regards, Inés
  2. Thank you Morten! It is really interesting that DTU is conducting so much research on this topic! Regarding my question, Windpro gives the option to calculate wind shear from time series at various measurement heights. Without lidar, there are not many options because there are 3 heights aprox, but with lidar, I have many more options. I would like to know how many measurements heights (and maybe also which ones) should I input to get the most accurate wind shear exponent. Thank you! Best regards, Inés
  3. Dear Wasp team, For wind vertical profile, I normally let WASP extrapolate to hub height from measurement height. However, i have this case where extrapolation must be from 80m to 120m. Since I have lidar measurements for 3 months up to 240 m, I have decided to extrapolate manually. Could you give me some advice on which lidar measurements to use to calculate the vertical profile? For example should i exclude the highest (240m) or lowest (40 m) measurements? Thank you very much, Kind regards, Inés
  4. Hi, I was wondering if there is an option in wasp where i can get hourly results for net energy production of a wind farm for a full year. Maybe there is a script that gives this result? Thank you very much, Best regards Inés
  5. Hi, I am planning to do a WASP CFD calculation. I saw in the wasp course that the met mast must be covered with a tile too (besides covering the wind turbines). I am guessing that for validation purposes it is useful, but since the CFD solver only takes into account terrain features, do I really need to cover the met mast with a tile? Also, I have several met masts for this particular case. Thank you!

    Forest height

    Hi, Thank you very much for your fast reply, it was very useful. Do you recommend introducing the displacement height in the altimetry map in the map Editor, rather than substracting it to each turbine hub height in WASP?

    Forest height

    Dear Wasp team, I am in the process of modelling a wind farm that is located in a forest, so I have some questions regarding this topic: - First of all, what do you recommend to get the canopy height in order to calculate the displacement height? I have found this database: https://glad.earthengine.app/view/global-forest-canopy-height-2019 but I would like to know if you have recommendations on how to measure this value (besides going to the location and measuring, of course). - Secondly, I would like to know what is the canopy height at which we should start considering the area to be a forest in WASP. For example, for a sparse forest with 7m trees, should I calculate a displacement height or should I just input a very high roughness and forget about displacement height? Thank you!
  8. Hi, I am creating an Observed Wind Climate in Wasp Climate analyst and I have data for 6 years, and some of them are non consecutive. For example, I have 2012 and 2014 but not 2013. When I choose view selected data, WACA "joins" the last measurement from 2012 to the first one from 2014 to recreate 2013 data. Is this right? I dont want the program to do this. How can I use these years as independent data? Thank you very much Inés
