1. 1. Evaluating the accuracy of NEWA, ERA5 and NORA3 in predicting onshore wind conditions: a comparative study using ICOS meteorological mast data in Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Svetlana Kuru; [2024]
   Keywords : NEWA; ERA5; NORA3; wind speed; wind distribution; correlation coefficient;

   Abstract : The ECMWF Reanalysis v5 (ERA5), the New European Wind Atlas (NEWA), and the 3 km Norwegian Reanalysis (NORA3) are reference datasets that are available for industry and research. The resolution of 3km in both the NORA3 and NEWA datasets sets them apart, while ERA5, with its 31km resolution, continues to serve as a reliable data source that is widely used in the industry.
