  1. 1. Evaluation of probabilistic forecasts in Uppsala and its potential use in winter road maintenance

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

    Author : Elisabet Johansson; [2023]
    Keywords : forecast evaluation; ensemble system; MetCoOp; winter road maintenance; snow removal; utvärdering; ensembelprognos; MetCoOp; snöröjning; vinterväghållning;

    Abstract : Efficient winter road maintenance is crucial for safety and societal function during the winter months in Sweden. This report aims to evaluate the MetCoOp ensemble system CMEPS and investigate its potential use as a basis for formulating criteria for snow removal that accounts for forecasted weather. READ MORE

  3. 2. Applying spatially and temporally adaptive techniques for faster DEM-based snow simulation

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Simon Andreasson; Linus Östergaard; [2023]
    Keywords : Real-time simulation; DEM; GPU; Games; Computer graphics; Realtidssimulering; DEM; GPU; Spel; Datorgrafik;

    Abstract : Background. Physically-based snow simulation is computationally expensive and not yet applicable to real-time applications. Some of the prime factors for this cost are the complex physics, the large number of particles, and the small time step required for a high-quality and stable simulation. READ MORE

  4. 3. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Thibault Desjonquères; [2022]
    Keywords : Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

    Abstract : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. READ MORE

  5. 4. Effects from Firn Density on Radar Derived Depth to Perennial Firn Aquifer, Lomonosovfonna, Svalbard

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

    Author : Daniel Estmark; [2022]
    Keywords : Perennial Firn Aquifer; Glacier; Svalbard; Mass balance; GPR; Lomonosovfonna; Flerårig firn akvifär; glaciär; Svalbard; massbalans; GPR; Lomonosovfonna;

    Abstract : As the climate is changing, there are clear impacts on the mass balance of glaciers. A glacier can be defined as the result of sufficient accumulation, in the form of snow and rain, compared to its ablation, the different types of glacial loss, a balance that then determines the size of the glacier.

  6. 5. Measurement of the snow accumulation in Antarctica with a neutrino radio detector and extension to the measurement of the index-of-refraction profile

    University essay from Uppsala universitet/Högenergifysik

    Author : Jakob Beise; [2021]
    Keywords : Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Abstract : High-energy neutrino physics offers a unique way to investigate the most violent phenomena in our universe. The detection of energies above E > 1017 eV is most efficient using the Askaryan effect, where a neutrino-induced particle shower produces coherent radio emission that is detectable with radio antennas.
