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

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Ellen Grace Soroka; [2023]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Influence from long-distance transport, local sources and precipitation on black carbon concentrations at a rural background field station in southern Sweden

   Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Kit Ming Yam; [2019]
   Nyckelord :Black carbon; black carbon concentrations; Hyltemossa station; Aethalometer; HYSPLIT; long-distance transport; local sources; precipitation; Physics and Astronomy; Earth and Environmental Sciences;

   Sammanfattning : The year 2018 was the first complete year with aerosol observations at the rural background station Hyltemossa in southern Sweden. The aim of this thesis was to analyse and investigate the influence from long-distance transport (LDT) aerosols, local sources and precipitation on the black carbon (BC) mass concentration by utilising the Aethalometer and the HYSPLIT model, which estimated the BC mass concentration ([BC]) and simulated the origin of the LDT air masses to Hyltemossa, respectively.
