ESDU 84030 provides tables of values of longitudinal turbulence intensities at 25 height intervals up to 400 m (1310 ft) above flat terrain for various site terrain roughnesses. The values@ which are based on the relationships developed in ESDU 82026 and 83045@ apply to sites where the roughness is uniform upwind@ or where either one or two changes in roughness occur upwind. ESDU 84030 complements ESDU 84011 by providing values of intensity for all cases of a single roughness change for which ESDU 84011 provides wind speed data. ESDU 01008 introduces a computer program that calculates the values given here using the full methods from which the simplified methods of ESDU 82026 and 83045 were derived; that program also includes topographic effects
