Abstract

The instrumentation development roadmap provides a guide on which measurements, and instruments, are important for future field campaigns to meet both the science objects and validation plans for their successful execution. The roadmap ensures the measurements are of sufficient type and resolution to meet science objectives and validation needs essential to the campaigns. The roadmap includes measurement categories ranging from instruments that need to be created to existing instruments essential to the field campaigns. The creation of the instrumentation development roadmap builds upon the previous Atmospheric to Electrons (A2e) validation work and formation of the American WAKE experimeNt (AWAKEN) science objectives. A process was created that maps between the (1) instrument measurement categories, (2) physical phenomena important to wind turbines, wind plants, and meso-scale forcing, (3) AWAKEN science objectives, and (4) near-term validation requirements for high-fidelity models (HFM). This document outlines the process that was developed in mapping between these dimensions of criteria as well as which measurement categories are most important for capturing the AWAKEN science objectives, Rotor Aerodynamics Aeroelastics, and Wake (RAAW) experiment validation objectives, and near-term HFM validation needs. The process established for creation of these measurement recommendations can easily be extended to additional campaigns by creating a mapping between the importance of the listed phenomena to the objects of the campaign and using the established mapping between how well the measurement categories capture the wind turbine, wind plant, and mesoscale phenomena. Additionally, the measurement categories were mapped to the HFM validation needs (Ref) to sort which measurement categories are most important for capturing model validation needs and add an additional approach to alleviate biases from a purely experimental or modeling perspective. These processes indicate which types of measurements or platforms are most important for achieving the objectives of these campaigns. To transition from measurement categories to specific instrumentation recommendations, a feasibility score was created specific to each instrument indicating its suitability for capturing the measurement need, its development cost and time, development uncertainty, and logistics for deployment. Combining the measurement category with the feasibility score provides a total score recommending which instruments are important for development and use in the field campaigns. Exact score and ranking are less important than the grouping of instruments near the top since all instruments included in the process are important to wind energy field tests.
