  1. 16. Improving Visibility Forecasts in Denmark Using Machine Learning Post-processing

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : August Thomasson; [2023]
    Keywords : visibility forecast; fog; machine learning; numerical weather predicition; XGBoost; Random Forest; siktprognos; dimma; maskininlärning; numerisk vädermodell; XGBoost; Random Forest;

    Abstract : Accurate fog prediction is an important task facing forecast centers since low visibility can affect anthropogenic systems, such as aviation. Therefore, this study investigates the use of Machine Learning classification algorithms for post-processing the output of the Danish Meteorological Institute’s operational Numerical Weather Prediction (NWP) model to improve visibility prediction.

  3. 17. Meteorological Causes for Wind Power Ramps: A Comparison between four sites in Sweden

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Anabelle Engert; [2023]
    Keywords : meteorology; mesoscale; wind energy; wind power ramps;

    Abstract : Wind energy as renewable energy will be crucial in ensuring future energy supply. Foundation for agood implementation of wind power output in the electrical grid are wind forecasts. Especially windpower ramp forecasting is important for an effective generation of wind power energy by wind parks. READ MORE

  4. 18. Analysis of performance data of wind turbines for polar regions

    University essay from Uppsala universitet/Högenergifysik

    Author : Arnau Serra Garet; [2023]
    Keywords : ;

    Abstract : The Radio Neutrino Observatory in Greenland is situated at Summit Station. Due to its isolatedlocation the main power to support the autonomous radio stations is solar energy. However,during the winter months when there is no sun another strategy needs to be found. READ MORE

  5. 19. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Margot Jeanne Knapen; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

    Abstract : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. READ MORE

  6. 20. A Comparative Analysis of Database Management Systems for Time Series Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tove Verner-Carlsson; Valerio Lomanto; [2023]
    Keywords : Database Management Systems; PostgreSQL; TimescaleDB; MongoDB; Time Series; Database Comparison; Performance Analysis; Databashanteringssystem; PostgreSQL; TimescaleDB; MongoDB; Tidsserier; Databasjämförelse; Prestandaanalys;

    Abstract : Time series data refers to data recorded over time, often periodically, and can rapidly accumulate into vast quantities. To effectively present, analyse, or conduct research on such data it must be stored in an accessible manner. For convenient storage, database management systems (DBMSs) are employed. READ MORE
