  1. 1. Microsatellite Constellation for Wildfire Monitoring

    University essay from KTH/Geoinformatik

    Author : Citlali Bruce Rosete; [2022]
    Keywords : microsatellite; shortwave infrared sensor; active fire monitoring; burned area detection; satellite constellation; mikrosatellit; kortvågig infraröd sensor; aktiv brandövervakning; detektion av brandhärjat område; satellitkonstellation;

    Abstract : I flera års tid har antalet svåra och okontrollerade skogsbränder ökat i antal. Det finns ett behov av att detektera skogsbränder med hjälp av satelliter som har högre tidsupplösning samt högre geometrisk upplösning än de satelliter som är i bruk idag. READ MORE

  3. 2. Analytical Methods for High Molecular Weight UV Stabilizers

    University essay from KTH/Kemi

    Author : Elin Ljungström; [2022]
    Keywords : hindered amine light stabilizers; light stabilizers; polyolefins; LC-MS; HPLC; hindrade aminljusstabilisatorer; ljusstabilisatorer; polyolefiner; LC-MS; HPLC;

    Abstract : Utomhusprodukter gjorda i plast är sårbara för nedbrytning på grund av UV-energi från solljus. För att stoppa denna fotonedbrytning används UV-stabilisatorer i plastmaterial; en av huvudkategorierna är hindrade aminljusstabilisatorer (HALS, hindered amine light stabilizers). READ MORE

  4. 3. Large-Scale Atmospheric Drivers of Extreme Temperature Anomalies During Springtime in the Arctic

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

    Author : Linnea Barreng; [2022]
    Keywords : Meteorology; Temperature extremes; Arctic; Jet stream; Rossby waves; Spring; Meteorologi; Arktis; Extremväder; Jetström; Rossbyvågor; Vår;

    Abstract : In this project warm extreme temperature events in the Arctic region during the spring months March, April and May were identified and analysed. In the analysis daily average NCEP reanalysis data from NOAA/OAR/ESRL PSL format was used. READ MORE

  5. 4. Glacial lakes in the Torneträsk region, northern Sweden, are key to understanding regional deglaciation patterns and dynamics

    University essay from

    Author : Karlijn Ploeg; [2022]
    Keywords : deglaciation; glacial geomorphology; LiDAR; glacial lakes; Torneträsk;

    Abstract : The prospect of sea level rise due to melting ice sheets affirms the urgency of gaining knowledge on ice sheet dynamics during deglaciation. The Fennoscandian Ice Sheet serves as an analogue, whose retreat can be reconstructed from the geomorphological record. READ MORE

  6. 5. Bow shock current closure to Earth's polar ionosphere - A statistical study using AMPERE and OMNI data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Eva Krämer; [2021]
    Keywords : ;

    Abstract : The bow shock current is hypothesized to connect to the Earth's magnetosphere on open field lines and to contribute as a field aligned current to the polar ionospheric currents. In order to investigate this, two years of AMPERE data are used to compute the average region 1 currents, and average currents within the polar cap boundary, under different interplanetary magnetic field (IMF) clock angles and IMF magnitudes.
