Metocean Conditions at Utsira Nord with NORA3 (1982-2022)

Utsira Nord Dataset

Description

This dataset focuses on metocean conditions at Utsira Nord (UN), an offshore Norwegian area located in deep-sea waters. The dataset contains hourly time series data from 1982 to 2022 for each grid point in the area, making it highly valuable for long-term climate studies and the development of floating offshore wind turbines.
