Max. 2000 char.) The Wind Atlas Analysis and Application Program (WAsP) is a PC-program for horizontal and vertical extrapolation of wind data. The program contains a complete set of models to calculate the effects on the wind of sheltering obstacles, surface roughness changes and terrain height variations. The analysis part consists of analysis of raw wind data (speed and direction) and generation of wind atlas data. The wind atlas data set can subsequently be applied for estimation of the wind climate and wind power potential, as well as siting of specific wind turbines. The program comes with a User’s Guide consisting of an introduction to the program, a description of the hardware requirements and installation procedure, a program reference section and a User’s Guide. This report describes the WAsP Utility Programs package, which contains a number of auxiliary programs to analyze, transform, view and plot WAsP data.
