  1. 1. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

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

    Författare :Soraya Hosseinvash Azari; [2023]
    Nyckelord :Physical Geography; Ecosystem Analysis; noise simulation; traffic; Nord2000 model; building façade types; roof configurations; geospatial data; 3CIM; SoundPLAN; acoustic properties; urban areas; 3D city model; Earth and Environmental Sciences;

    Sammanfattning : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. LÄS MER

  3. 2. 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

  4. 3. Analyzing Meteorological Relationships to Aerosols in China

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

    Författare :Carl Svenhag; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Meteorological conditions are influenced everyday by air-bound aerosols and pollution in the atmosphere, and understanding these processes from micro to synoptic scale, is essential for forecasting and creating high resolution weather models. In this study, three different experimental weather models are analysed to provide some understanding on how various meteorological parameters are influenced by modelling atmospheric aerosols.

  5. 4. Aerosol Measurements and Analysis

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Maj Blomdell; Ida Lundin; [2012]
    Nyckelord :Aerosol particles; particle size distributions; diurnal variations.; Physics and Astronomy;

    Sammanfattning : Abstract The greatest source of hazardous airborne particles in an urban environment comes from traffic exhaust. Air pollution has a great impact on human health; estimated to cause 1.3 million deaths worldwide per year. About half of all mortality caused by air pollution can be linked to motorized traffic.

  7. 5. A comparison of the temperature climate at two urban sites in Uppsala

    Magister-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Paulina Larsson; [2001]
    Nyckelord :surface temperature; urban heat island; site comparison; urban meteorology;

    Sammanfattning : Meteorological data from two observation sites in Uppsala, the Observatory Park (Op) andthe Geocentre (Gc), during the period January 1998 to September 2000, have been used tocheck the differences in the temperature climate at the two places. Since Op is situatedcloser to the city centre than Gc the site is thought to be more affected by the so calledurban heat island effect. LÄS MER
