1. 1. Fragmentation in graupel snow collisions

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Martanda Gautam; [2022]
   Keywords : Ecosystem Analysis; Clouds; Snow; Graupel; SIP; Fragmentation; CKE; Rime Fraction; Earth and Environmental Sciences;

   Abstract : Aircraft observations of precipitating clouds with cloud top temperatures higher than -38°C have revealed that Secondary Ice Production (SIP) is responsible for presence of majority of ice particles. One such SIP mechanism is fragmentation via collisions between ice particles. READ MORE

3. 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

4. 3. Atmospheric soot particle transformation from urban to rural

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

   Author : Fredrik Johansson; [2018]
   Keywords : Aerosol; soot; atmosphere; Physics and Astronomy; Earth and Environmental Sciences;

   Abstract : The main objective of this work was to investigate if there is a contribution of aerosol from the urban region of Copenhagen at the rural station Vavihill. This was done by analyzing measurement data between 1st of January and the 28th of February 2013 measured with a Dierential Mobility Particle Sizer (DMPS), Soot Particle Aerosol Mass Spectrometer (SP-AMS), a Cloud Condensation Nuclei Counter (CCNC) and a NOx-analyzer.
