Perdigão 2015: methodology for atmospheric multi-Doppler lidar experiments.

The long-range and short-range WindScanner systems, multi-Doppler lidar instruments, can map the turbulent flow around a wind turbine and at the same time measure mean flow conditions over an entire region such as a wind farm. As the WindScanner technology is novel, performing field campaigns with the WindScanner systems requires a methodology that will maximize the benefits of conducting WindScanner-based experiments. Such a methodology is presented and discussed through its application in a pilot experiment that took place in a complex and forested site in Portugal where for the first time the two WindScanner systems operated simultaneously. The methodology consists of 10 steps. The steps are presented and the implementation of each step is demonstrated. Overall, the demonstration of the methodology in the pilot experiment resulted in a detailed site selection criteria, well-thought-out experiment layout, novel flow mapping methods and high quality flow observations, all of which are presented in this paper.
