1. 1. Verification of the local similarity theory above forests

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Yasmin Hubmann; [2021]
   Keywords : Forest Meteorology; Boundary Layer Meteorology; Wind Energy; Local Similarity Theory; Monin–Obukhov Similarity Theory; Flux-Gradient Formulation; Richardson Number Formulation; Turbulence Statistic; Rotor Equivalent Wind Speed; Grenzschicht-Meteorologie; Forstmeteorologie; Windenergie; Lokale Ähnlichkeitstheorie; Monin–Obukhov’sche Ähnlichkeitstheorie; Fluss-Gradient-Ähnlichkeit; Gradient-Richardson-Zahl Beziehung; Turbulenzcharakteristiken; Rotor-äquivalente Windgeschwindigkeit; Skogsmeteorologi; Gränsskiktsmeteorologi; Vindenergi; Lokal Similaritetsteori; Monin–Obukhov Similaritetsteori; Flöd-Gradient Relation; Richardson Gradienttal Relation;

   Abstract : In this study, the local similarity theory functions were calculated with two different approaches and on the other hand the mean hub height wind speed was compared with the rotor equivalent wind speed. Both calculations are based on two independent data-sets from measurement campaigns Hornamossen and Ryningsnäs which were conducted in the south of Sweden between May 2015 and June 2017, and November 2010 and February 2012.

3. 2. Study of spatial and temporal variation of atmospheric optical parameters and their relation with PM 2.5 concentration over Europe using GIS technologies

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Panagiotis Symeonidis; [2017]
   Keywords : aerosols; air quality; satellite remote sensing; GIS; geography; Geographical Information Systems; particulate matter; Aerosol Optical Depth; MODIS; Earth and Environmental Sciences;

   Abstract : The purpose of this study was to examine the use of remote sensing aerosol data as an estimator of ground level fine particulate matter concentration (PM 2.5). In order to examine this possible relation, daily MODIS Aerosol Optical Depth (AOD) data were used, collected for an entire year. READ MORE

4. 3. RETRIEVING THE HEIGHT OF THE PLANETARY BOUNDARY LAYER OVER STOCKHOLM FROM LIDAR MEASUREMENTS

   University essay from Lunds universitet/Fysiska institutionen

   Author : Ewa Johansson; [2013]
   Keywords : Planetary Boundary Layer; Meteorology; weather forecast; Raman LIDAR; Physics and Astronomy;

   Abstract : LIDAR data from the Polly system on the roof of the Arrhenius laboratory at Stockholm University are used to determine the planetary boundary layers (PBL) height distribution. To this end, a wavelet covariance transform method is employed to analyze LIDAR measured data signals from the years 2011-2012. READ MORE

5. 4. Flux Attenuation due to Sensor Displacement over Sea

   University essay from Institutionen för geovetenskaper

   Author : Erik Nilsson; [2007]
   Keywords : Meteorology; Attenuation; Sensible Heat Flux; Eddy Correlation; Marine Atmospheric Boundary Layer; Complex Error Function;

   Abstract : In this study the flux attenuation due to sensor displacement has been investigated over sea using an extensive set of data from the "Ocean Horizontal Array Turbulence Study". All previous investigations of the flux attenuation have been performed over land. READ MORE

6. 5. Influence of fog on stratification and turbulent fluxes over the ocean

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Linda Lennartsson; [2004]
   Keywords : coastal meteorology; fog; turbulent fluxes; stratification;

   Abstract : In this thesis a case of advection fog over the Baltic Sea is studied. The period examined is from June 5th to 7th 1995. Data is taken from the instrumented mast, situated on the island Östergarnsholm, a small and flat island without trees outside of Gotland. READ MORE
