Interpolation method for wind speed and wind direction

Post by Lance »

Dear ENVI-met team,

In the full forcing mode, the hourly epw data will be interpolated to 30 mininutes data. From the context chart below, I can see that the data of air temperature, specific humidity, sw direct Rad, sw diffuse Rad and longwave Rad are interpolated by using linear interpolation. But I am not so sure about the interpolation method for wind speed and wind direction. Would you mind explaining about this?

Hi Lance,

Wind speed and direction are calculated into wind components U and V which are then interpolated linearly.

Best regards,
Tim
