  1. 1. Cloud Observations at a Coastal site – Analysis of Ceilometer Measurements from Östergarnsholm, Sweden

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

    Författare :Aron Stenlid; [2019]
    Nyckelord :Ceilometer; Stratocumulus; cloud base height; LCL; DLS; upwelling; cloud cover;

    Sammanfattning : In this study, four and a half months of ceilometer data from Östergarnsholm are used to analyze cloud related to processes in the boundary layer. Measurements are divided into two categories, which are defined by wind direction: a continental and a marine sector. LÄS MER

  3. 2. A Study of the Short-term Variability of Seawater pCO2 near Östergarnsholm

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

    Författare :Jennie Persson Söderman; [2014]
    Nyckelord :coastal upwelling; carbon dioxide; air–sea exchange; Baltic Sea measurements;

    Sammanfattning : In this study, an analysis of upwelling and biological activities impact on the seawater pCO2 variability was done to improve the knowledge about the pCO2 variability in seawater in the Baltic Sea. During upwelling activity, CO2 rich waters are upwelled to the surface. LÄS MER

  4. 3. Variability of turbulent fluxes (momentum, heat and CO2) during Upwelling conditions. A case study

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

    Författare :Carlos Román Cascón; [2010]
    Nyckelord :CO2 fluxes; upwelling; marine boundary layer; turbulent fluxes;

    Sammanfattning : Measurements of turbulent fluxes (momentum, sensible heat, latent heat and CO2) at two different heights were studied from data of a tower at Ostergarnsholm Island (Baltic Sea) during one week, while calculations using bulk formulations of fluxes were done with measurements in the tower and in two buoys moored at different locations. Different behaviors are found for the different fluxes. LÄS MER

  5. 4. The Behaviour of the Latent Heat Exchange Coefficient in the Stable Marine Boundary Layer

    Uppsats för yrkesexamina på grundnivå, Institutionen för geovetenskaper

    Författare :Kristina Lindgren; [2008]
    Nyckelord :Latent heat flux; Sensible heat flux; Exchange coefficient; Neutral exchange coefficient; Turbulent Fluxes; Marine Boundary Layer; Stable Stratification; Air-sea interaction; Dimensionless profile functions; Östergarnsholm;

    Sammanfattning : Knowledge of the turbulent fluxes at the sea surface is important for understanding the interaction between atmosphere and ocean. With better knowledge, improvements in the estimation of the heat exchange coefficients can be made and hence models are able to predict the weather and future climate with higher accuracy. LÄS MER

  7. 5. CO2-Variation over the Baltic Sea

    Magister-uppsats, Institutionen för geovetenskaper

    Författare :Gustav Åström; [2007]
    Nyckelord :CO2; Baltic Sea;

    Sammanfattning : The increasing levels of the greenhouse gas carbon dioxide (CO2) in the Earths atmosphere, caused by human release of CO2, has made it desirable to understand the factors determining the CO2-variation because of CO2’s warming effect on the Earths temperature which will change the premises of all life on earth. The purpose of this investigation is to understand the effects of the largest factors of influence on the CO2-concentration - like sea, vegetation and anthropogenic outlets - in the Baltic Sea region, and possible surprises from the results.
