   Sammanfattning : While it is not the most abundant greenhouse gas, a significant portion of the greenhouse effect is caused by methane. The amount of methane in the atmosphere is increasing, indicating that there is a continuous source of methane to the atmosphere. LÄS MER

3. 2. An Investigation of the Relation between Sea Breeze Circulation and Diurnal Variation of Methane at a Swedish Lake

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

   Nyckelord :WRF model; Sea breeze; methane emission; diurnal variation; internal boundary layer; WRF-modellen; sjöbris; metanemission; dygnsvariation; internt gränsskikt;

   Sammanfattning : Methane measurements over lake Tämnaren show a pronounced diurnal variation with high values at night and low values during daytime. The atmosphere over the lake and its surroundings is simulated with two different settings and resolutions of the WRF model during a period of eight days in May 2011 to investigate if a lake/land breeze circulation could be the cause of the observed methane variation.
