The Wind Atlas Analysis and Application Program, WAsP, is a PC program designed for predicting wind climates and power productions from wind turbines and wind farms. Predictions are based on wind data measured at stations in the same region. The program includes a complex terrain flow model, a roughness change model and a model for sheltering obstacles.

The WAsP program is developed and distributed by the Wind Energy Department at Risø National Laboratory, Denmark. It is primarily used in:

•  Wind farm production and efficiency
•  "Micro-siting" of turbines
•  Power production calculations
•  Wind resource mapping and climate estimation
•  Wind data analysis
• Wind atlas generation 

In this section we will talk about the various aspects of WAsP and how using this modeling tool was integral to our project.
