For this correction, one should at least know the site specific Annual Atmospheric Temperature & altitude values of the site. There is no quick way to get the Site Spc AD. By applying these two parameters in the AIR DENSITY CALCULATOR (WAsP) we can get the site specific (or Hub height) air density values. However site specific air density derived from this method in not so precise. The WAsP AIR DENSITY CALCULATOR gives the results by referring " Air density table" (Temp against Elevation). To get the correct Site specific Air density, one should have the site mast measured Atmph Pressure & Temperature values (min 1 yr period). after processing this, any wind data analysis tool will give the precise site Spc AD. - And to do a better energy calculation we should apply this site Spc AD to the Power curve by doing leaner interpolation [IEC].

Yes, we are desperately waiting for WAsP-CFD model & expecting that Risø may add some additional small tools [GUI] , like, inter-turbine measurement scale, facility to place desired radius circles. " Site description" or WTG ID label display in the map window (Within WAsP). - Secondly, also expect that WAsP-CFD to do automatic RIX corrections for each location. Improvement in wake losses calculation. Liberty to use multiple wind mast data for one site.
