  1. 1. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ellen Grace Soroka; [2023]
    Keywords : Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Abstract : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. READ MORE

  2. 2. Snow-graupel collisions in clouds: a newly derived formulation for breakup of single crystals

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Victor Craig van der Brug; [2022]
    Keywords : Physical Geography and Ecosystem Analysis; Secondary Ice Production; Ice Cloud Number Concentration; Cloud Ice; Ice-Ice Collisions; Snow Crystal; Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Abstract : The observed and well-known discrepancy between concentrations of ice nucleating particles in the environment and the concentrations of ice particles in clouds show that there are additional ‘secondary’ processes enhancing the concentrations of ice particles. In present-day modelling of weather and climate, such processes are mostly overlooked and thus a cause for uncertainty. READ MORE

  3. 3. Evaluating forest wildfire effect on tree increment patterns for boreonemoral forests in Sweden: A pilot study using remote sensing

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Joanna Eaton; [2022]
    Keywords : Physical Geography and Ecosystem analysis; Remote sensing; Sentinel-2A; Forest wildfires; dNBR; NDVI; dNDVI; Dendrochronology; Atmospheric science and biogeochemical cycles; Earth and Environmental Sciences;

    Abstract : The release of anthropogenic greenhouse gases (GHGs) has substantially increased the global mean surface air temperature. Increases in global mean surface air temperature will lead to warmer and drier conditions, promoting more frequent, long-lasting, intense forest wildfires. READ MORE
