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

3. 2. Planetary Boundary Layer Height Variations Over the Tibetan Plateau in Relation to Local Climate Variables and Large-Scale Circulation

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Nils Slättberg; [2020-09-09]
   Keywords : ;

   Abstract : The lowest layer of the Earth's atmosphere, the planetary boundary layer (PBL), may reach extremely high above the Tibetan Plateau (TP). Moreover, the TP is a hotspot region for climate interactions, exerting far-reaching in uences on atmospheric conditions. READ MORE

4. 3. Planetary boundary layer height measurements in a rural environment in southern Sweden - Relation to meteorological parameters and aerosol particle concentrations

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

   Author : Ellen Carneheim; [2020]
   Keywords : Physics and Astronomy;

   Abstract : The aim of this project is to analyse planetary boundary layer height (BLH) measurements from the Hyltemossa research station and find their dependence on seasonality, time of day, and air temperature. Further, investigation was made into the correlation between mass concentration of particulate matter with equivalent diameter... READ MORE

5. 4. Study of spatial and temporal variation of atmospheric optical parameters and their relation with PM 2.5 concentration over Europe using GIS technologies

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Panagiotis Symeonidis; [2017]
   Keywords : aerosols; air quality; satellite remote sensing; GIS; geography; Geographical Information Systems; particulate matter; Aerosol Optical Depth; MODIS; Earth and Environmental Sciences;

   Abstract : The purpose of this study was to examine the use of remote sensing aerosol data as an estimator of ground level fine particulate matter concentration (PM 2.5). In order to examine this possible relation, daily MODIS Aerosol Optical Depth (AOD) data were used, collected for an entire year. READ MORE

6. 5. Quantifying the Shadow Effect between Offshore Wind Farms with Idealized Mesoscale Models and Observed Wind Data

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : David Werner; [2016]
   Keywords : Shadow effect; offshore wakes; atmospheric stability; analog ensemble; wake forecasting; idealized mesoscale modeling; Weather Research Forecast WRF model; downscaling; North Sea; Princes Amalia; Egmond aan Zee;

   Abstract : Two post processing methods for quantifying the shadow effect of the offshore wind farm Princes Amalia (PA) onto Egmond aan Zee (OWEZ) wind farm are analyzed and benchmarked. The first method is the author’s proposed shadow effect determination method (SEDM), which quantifies an offshore wind farm’s shadow effect based on mesoscale WRF (Weather Research Forecast) idealized modeling and the observed frequency of the analyzed site’s wind conditions.
