  2. 2. Formation, ageing and thermal properties of secondary organic aerosol

    Detta är en avhandling från Stockholm : Univ

    Författare :Eva U. Emanuelsson; Göteborgs universitet.; Gothenburg University.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; volatile organic compounds; biogenic; anthropogenic; secondary organic aerosol; troposphere; volatility; ozone;

    Sammanfattning : In order to properly represent and predict the effects of aerosol in climate systems, an accurate description of their formation and properties is needed. This thesis describes work done to increase the knowledge of processes and properties of atmospherically relevant secondary organic aerosol (SOA) from both biogenic and anthropogenic origin. LÄS MER

  4. 4. Enhancing Tropospheric Humidity Data Records from Satellite Microwave and Radiosonde Sensors

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Isaac Moradi; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CDR; climate; microwave; radiosonde; water vapor; remote sensing; antenna; homogenization; humidity; meteorology; troposphere; radio-frequency;

    Sammanfattning : Water vapor is the most dominant greenhouse gas and plays a critical role in the climate by regulating the Earth's radiation budget and hydrological cycle. A comprehensive dataset is required to describe the temporal and spatial distribution of water vapor, evaluate the performance of climate and weather prediction models in terms of simulating tropospheric humidity, and understand the role of water vapor and its feedback in the climate system.

  5. 5. Studies of Tropospheric and Stratospheric Aerosol using Ion Beam Analysis

    Detta är en avhandling från Div. of Nuclear Physics, Dept. of Physics, Lund Institute of Technology, Lund University, P.O. Box 118, SE-221 00 Lund, Sweden

    Författare :Giorgos Papaspiropoulos; Lund University.; Lunds universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmosphere; Aerosols; troposphere; stratosphere; ion beam analysis; PIXE; impactors; particulate sulphur; chemical speciation; elemental analysis; thermography; Physics; Nuclear physics; Fysik; Metrology; Kärnfysik; physical instrumentation; Metrologi; fysisk instrumentering; Fysicumarkivet A:2001:Papaspiropoulos;

    Sammanfattning : Atmospheric aerosol particles are believed to have an impact on the radiative forcing of the earth's surface. The predicted results indicate a net cooling effect on the global climate, however there are few studies available to substantiate this and experimental data are needed. LÄS MER
