  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

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Svetlana Kuru; [2024]
    Nyckelord :NEWA; ERA5; NORA3; wind speed; wind distribution; correlation coefficient;

    Sammanfattning : 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.

    Sammanfattning : In this thesis the aerodynamic loads for maximum power output at acceptable fatigue loads on a 1.5MW onshore wind turbine are examined. LÄS MER

  5. 4. Projecting invasive species using remote sensing and spatial explicit models

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Astrid Zimmermann; [2018]
    Nyckelord :Physical Geography; Ecosystem Analysis; Rosa rugosa; invasive species; aerial images; growth rate; modeling; cellular automata; Earth and Environmental Sciences;

    Sammanfattning : An evaluation of the current and previous Rosa rugosa growth on Kieler Ort, Germany, with the aim to predict the rose coverage in future, under consideration of environmental factors. Kieler Ort, a rather isolated island in the southwest Baltic Sea is representing a unique environment which is protected for its landscape, nature, flora and fauna and serves as a bird sanctuary.

  7. 5. Wind resource assessment for posibel wind farm development in Dekemhare and Assab, Eritrea

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Teklebrhan Negash; [2018]
    Nyckelord :Wind resource assessment; Wind farm; Annual Energy Aroduction; Assab wind site; Dekemahre wind site; Eritrea; Weibull distribution; Wind rose; Wind power density; Capacity factor.;

    Sammanfattning : Recently wind resource assessment studies have become an important research tool to identify the possible wind farm locations.  In this thesis work technical analysis was carried out to determine the wind resource potential of two candidate sites in Eritrea with help of suitable software tools.
