  1. 1. Interpreting and composing SAGE II-III satellite data with a cloud algorithm for stratospheric aerosols

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

    Författare :Carl Svenhag; [2020]
    Nyckelord :atmospheric science; Aerosol; cloud physics; stratosphere; satellite observations; SAGE; Climate change; Earth and Environmental Sciences;

    Sammanfattning : Tolkning och kvantifiering av strålningseffekter pga. atmosfäriska partiklar är en signifikant del av IPCC’s modellering av hur tidigare klimat förändrats och hur förändringar i framtiden kommer se ut. LÄS MER

  2. 2. Lung Deposition of Airborne Particles - Resolved in a Single Breath

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Amalia Larsson Hurtig; [2020]
    Nyckelord :Aerosols; Airborne particles; Inhalation; Lung deposition; Respiratory tract deposition; Technology and Engineering;

    Sammanfattning : Exposure to airborne particulate matter has been declared to cause cardiovascular and respiratory disease as well as cancer. By understanding how the aerosol particles deposit in our respiratory tract, we can understand how the exposure to airborne particles affect our health. LÄS MER

  3. 3. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height

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

    Författare :Elin Kindlundh; [2020]
    Nyckelord :HARMONIE-AROME; ECMWF-IFS; WRF; verification; visibility; cloud base height; HARMONIE-AROME; ECMWF-IFS; WRF; verifikation; sikt; molnbashöjd;

    Sammanfattning : Visibility and cloud base height are two important parameters within aviation meteorology and verification of operational numerical weather prediction (NWP) models with regard to these two parameters is therefore important. Visibility is often parameterized through an extinction coefficient, which is dependent on for example liquid or ice water content, however it also depends on the humidity, precipitation intensity and particle concentration.

  4. 4. Evaluation of a heated inlet to reduce humidity induced error in low-cost particulate matter sensors

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Piotr Czernicki; Mathias Kallmert; [2019]
    Nyckelord :particulate matter; optical particle counter; relative humidity; low-cost; pm sensor; heated inlet; Technology and Engineering;

    Sammanfattning : The number of low-cost particulate matter (PM) sensors available on the market has increased in recent years. They are affordable, compact and require no maintenance which means they easily can be deployed and utilized for real-time air monitoring. However, the accuracy of low-cost PM sensors has been reported to vary depending on several factors. LÄS MER

  5. 5. 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
