  1. 16. Analyzing Meteorological Relationships to Aerosols in China

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

    Author : Carl Svenhag; [2017]
    Keywords : Physics and Astronomy;

    Abstract : 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.

  3. 17. Joint use of Sentinel-1 and Sentinel-2 for land cover classification : a machine learning approach

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Miguel Gumersindo Castro Gomez; [2017]
    Keywords : Random Forest; temporal series; Physical Geography and Ecosystem analysisoptical; GEM; land cover classification; SAR; Earth and Environmental Sciences;

    Abstract : Reliable information on land cover is required to assist and help in the decision-making process needed to face the environmental challenges society has to deal with due to climate change and other driving forces. Different methods can be used to gather this information but satellite earth observation techniques offer a suitable approach based on the coverage and type of data that are provided. READ MORE

  4. 18. Emergency Communication

    University essay from Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Author : Abdulrahman Aburawi; Sarija Salic; [2015]
    Keywords : Shortwave radio; Disaster relief; Wireless communication; Smartphones; Telecommunication; Arduino; Embedded system; Radio; Kortvågsradio; Inbyggda system; Nödkommunikation; Trådlös kommunikation; Telekommunikation; Kortvåg; High frequency radio; HF radio; SW radio;

    Abstract : Even in the 21st century, modern communication technology is still affected by natural disasters and political turmoil which threaten people’s lives and make the internet or mobile phone networks unavailable for use. This work uses systems theory which resulted in a proof of concept system that uses shortwave radio technology to provide a one-way communication system. READ MORE

  5. 19. Soot particles from shipping: Analysing emission factors

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Nicklas Mauritzson; [2015]
    Keywords : Ship emission; emission factor; soot; black carbon; measurement; SECA; Gothenburg; Sweden; Earth and Environmental Sciences;

    Abstract : Emissions of air pollutants from shipping in Europe result in about 50 000 premature deaths every year. Soot particles, also called black carbon, are particularly hazardous to human health when inhaled. The adverse health effects are especially a danger in coastal areas, but the particles can travel further away with the wind. READ MORE

  6. 20. Meteorological differences between Rabots glaciär and Storglaciären and its impact on ablation

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Pia Eriksson; [2014]
    Keywords : glaciology; micro-climate; mass balance; surface energy balance; scandinavian glaciers;

    Abstract : In the Kebnekaise Massif, Northern Sweden, the west facing glacier, Rabots glaciär, is loosing volume at a significantly higher rate than east facing, Storglaciären. By analyzing data from automatic weather stations situated on the ablation area on the glaciers we investigated the effect of meteorological differences on ablation. READ MORE
