Abstract/Summary

A novel method to determine representative periods (typically a year) for the estimation of the longterm mesoscale wind resource has been proposed and compared to other recently published techniques. It provides a computationally lean while accurate solution of the problem of constructing long-term mesoscale wind maps through downscaling without having to go through a brute force procedure. Applications include a wider dissemination of mesoscale wind maps because of faster and cheaper execution, as well as greater flexibility for sensitivity analyses.
