  1. 11. Motion of icy grains originating in Saturn’s D-ring

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Institutionen för fysik och astronomi

    Author : Apostolos Kolokotronis; [2023]
    Keywords : ;

    Abstract : Saturn's rings have long been thought to provide the planetary atmosphere with infalling material, affecting both its chemical composition and physical properties (e.g. temperature). READ MORE

  3. 12. Cusp Aurora Appearing at the Dayside tip of Transpolar Arcs - Dependence on IMF and Dipole Tilt

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

    Author : Cecilie Holmen; Mattias Wang; [2023]
    Keywords : ;

    Abstract : The aurora is a direct consequence of the Earth’s magnetic field interaction withthe solar wind and the interplanetary magnetic field (IMF). In this study, we examine thelocation of the cusp aurora when accompanied by transpolar arcs (TPAs) with the goal to finda dependence on the IMF. READ MORE

  4. 13. A comparison of remote sensed semi-arid grassland vegetation anomalies detected using MODIS and Sentinel-3, with anomalies in ground-based eddy covariance flux measurements.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jason Craig Joubert; [2023]
    Keywords : Geography; GIS; Anomaly Detection; Remote Sensing; fAPAR; GDMP; GPP; MODIS; Sentinel-3; Earth and Environmental Sciences;

    Abstract : Remote sensed vegetation biophysical indicators are derived from various sensors and methods and contribute to the quantification of vegetation growth. They are used as inputs to early warning systems for crop yield estimation, thus improving crop management and food security. READ MORE

  5. 14. Forest, Tree, and Shrub limit responses to a century of climate change in Northern Norway

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Ella Björsbo; [2023]
    Keywords : Climate warming; growing season length; forest limit; tree limit; shrub limit;

    Abstract : Climate changes have been observed in the Northern Hemisphere during the last century, causing a longer growing season and upslope expansion of forest, tree, and shrub limits. Here, a long-term historical perspective was used as a tool for investigating how climate change has impacted woody plants at the forest, tree, and shrub limits across the study region. READ MORE

  6. 15. Effects of stratospheric wildfire smoke on ozone depleting substances and ozone levels in the northern midlatitudes

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

    Author : Christopher Grüner; [2023]
    Keywords : Physics and Astronomy;

    Abstract : The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. READ MORE
