  1. 1. The Role of Uni- and Multivariate Bias Adjustment Methods for Future Hydrological Projections and Subsequent Decision-Making

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Anna Merle Liebenehm-Axmann; [2024]
    Nyckelord :Bias adjustment methods; future hydrological climate projections; statistical analysis; future streamflow analysis; biasjusteringsmetoder; framtida hydrologiska projektioner; statistisk analys; framtida vattenförings analys;

    Sammanfattning : Climate models are essential for generating future climate projections. However, due to simplifications, the models can produce systematic differences between output and reality, which is referred to as model bias. Bias adjustment methods aim to reduce this error, which is important for making future projections more reliable. LÄS MER

  3. 2. Molns inverkan på satellitdetektion av vegetationsbränder i Sverige

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Marcus Letalick; [2022]
    Nyckelord :clouds; satellite detection; VIIRS; active fires; forest fire; grass fire; FRP; NOAA-20; Suomi-NPP; JPSS; moln; satellitdetektion; VIIRS; skogsbrand; gräsbrand; vegetationsbrand; FRP; NOAA-20; Suomi-NPP; JPSS;

    Sammanfattning : Results are presented from the 2021 test run of active fire detection using the Visual Infrared Imaging Radiometer Suite (VIIRS) instrument, that is currently onboard the polar satellites Suomi-NPP and NOAA-20. The test is performed by the Swedish Civil Contingencies Agency and the Swedish Meteorological and Hydrological Institute, in cooperation with local fire departments in Sweden. LÄS MER

  4. 3. Evaluation of Streamflow Predictions in an Ungauged Swedish Catchment : A Study of Håga River

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Hanna Pierrau; [2022]
    Nyckelord :Hydrology; Predictions in ungauged basins; Hydrological signatures; rainfall-runoff modelling; HBV; S-HYPE; hydrologi; uppskattningar i områden utan mätstation; hydrologiska signaturer; modellering; HBV; S-HYPE;

    Sammanfattning : The Håga river, located west of the Swedish city Uppsala, is currently without a proper gauging station. Knowing the streamflow is nonetheless important to, for example, be able to calculate the nutrient transport in the river. LÄS MER

  5. 4. Estimation of leaf area index in southern Sweden with optimal modelling and Landsat 7 ETM+Scene

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

    Författare :Pontus Olofsson; Richard Stenström; [2000]
    Nyckelord :cartography; pedology; geomorphology; physical geography; optical modelling; satellite imaging; remote sensing; leaf reflectance; climatology; naturgeografi; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Sammanfattning : Canopy reflectance models are used as a means of estimating vegetation parameters and simulating reflectance signatures of vegetation surfaces. A forest canopy reflectance model is tested on deciduous forest collections in southern Sweden. LÄS MER
