Selection and Use of Measured Winds, Temperature and Turbulence in AERMET

THRESHOLD WIND SPEED

The user is required to define a threshold wind speed (u_TH ). Although the current version of AERMOD can not accept a separate u_TH for offsite data, we believe that a separate u_TH should be selected for each data set being used.
