Hawaii Meteorology, Energy, and Transmission (MET) Toolkit
The Hawaii Meteorology, Energy, and Transmission (MET) Toolkit is the National Laboratory of the Rockies' (NLR) high-fidelity atmospheric dataset purpose-built to support long-term power system planning and operations across the Hawaiian Islands. Serving as the successor to the legacy National Offshore Wind (NOW-23) Hawaii dataset, this product delivers a unified, geometrically accurate meteorological record spanning 26 years (2000-2025) at 5-minute resolution. Processed using the Weather Research and Forecasting (WRF) model with the Yonsei University (YSU) planetary boundary layer scheme - validated against a comprehensive suite of lidar buoy and surface observations - the dataset corrects a geometric projection error identified in the legacy NOW-23 grid that introduced spatial scaling distortion across the Hawaiian domain. Delivering a comprehensive suite of atmospheric variables - including wind characteristics, temperature, pressure, and humidity - across a strictly standardized and validation-backed framework, the Hawaii MET Toolkit provides the reliable, long-term meteorological foundation required for renewable generation assessment, load modeling, transmission line rating, and resource adequacy planning in Hawaii's evolving grid.
