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

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

    Författare :Christopher Grüner; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. LÄS MER

  3. 2. Development of PSC detection tools using IRF lidar data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Oriol Peláez Mercadal; [2020]
    Nyckelord :atmospheric science; polar stratospheric clouds; lidar; data analysis;

    Sammanfattning : Polar stratospheric clouds (PSCs) play a crucial role in ozone depletion mechanisms. Thus, their observations are important to understand their formation processes and active effects towards the atmosphere. LÄS MER

  4. 3. Estimation of the potential BVOC emissions by the different tree species in Malmö

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

    Författare :Larissa Lisa Gesa Scholz; [2019]
    Nyckelord :BVOC emissions; isoprene; monoterpene; air quality; Malmö; Earth and Environmental Sciences;

    Sammanfattning : BVOC emissions from trees contribute to ozone and secondary aerosol formation and therefore have an impact on air quality. The two most abundant BVOCs emitted from trees are isoprene and monoterpenes. LÄS MER

  5. 4. Modeling of ozone and nitrogen oxides pollutions in urban air environments

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

    Författare :Henrik Reimer; [2018]
    Nyckelord :Ozone; Nitrogen oxides; NOx; Hydrocarbons; VOC; Urban environment; Model; Pollutions; Physics and Astronomy;

    Sammanfattning : As the air quality in urban environments is a rising problem, a deeper understanding of how air pollution is dependent on different factors is necessary. In these environments, there are different parameters that effect how the chemical reactions of the pollutants are proceeding. LÄS MER

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

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

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

    Sammanfattning : 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. LÄS MER
