The IMPOWR project (Improving the Mapping and Prediction of Offshore Wind Resources) was sponsored by the U.S. Department of Energy (DE-EE000537) and lead by SUNY’s Stony Brook University. Our goal was to improve the treatment of the boundary layer winds in mesoscale models, such as the Weather Research and Forecast (WRF) model, via measurements and ensemble modeling. The project used ocean and atmospheric measurements taken at an offshore meteorological tower (owned by Cape Wind) and by a Long-EZ research aircraft to validate the WRF model.
