(Master thesis / Masteroppgave, 2010)Forskning over de siste ti årene har etablert at dagens bakgrunnskonsentrasjon av bakkenær ozon er høy nok til å ha skadelig effekt på vegetasjon. Disse effektene inkluderer reduksjon i biomasseproduksjon, trevekst og ...
-
(Master thesis / Masteroppgave, 2020)Periods of unusually high or low temperatures have a significant impact on both nature and society at all times of the year. A possible change in frequency or persistence of such events would impact the wildlife as well ...
-
(Master thesis / Masteroppgave, 2019)Heavy rain events in the Arctic archipelago Svalbard can have a high impact on nature and settlements, and are predicted to become more frequent and intense in the coming decades. This thesis work focuses on heavy rain ...
-
(Master thesis / Masteroppgave, 2020)Helicopters are sometimes hit by lightning when flying offshore along the coast of Norway. Often, the helicopter’s presence is what triggers the lightning strike, and this phenomenon is called Helicopter Triggered Lightning ...
-
(Master thesis / Masteroppgave, 2009)A short range, limited area ensemble prediction system, LAMEPS, is currently in operational use at the Norwegian Meteorological Institute. It employs 3D-Var for 6 hourly data assimilation cycling for analysis of the control ...
-
(Master thesis / Masteroppgave, 2013)Arktis har vært, og er fortsatt, et utfordrende område for numeriske modeller for studier av fenomener knyttet til skyer. Mye av dette skyldes at skyer ikke blir simulert godt nok. Spesielt det å simulere underkjølt skyvann, ...
-
(Master thesis / Masteroppgave, 2009)We decided to take a fresh new look at the historical hydrographic data from the Environmental Working Group-atlas (EWG) in light of the recent dramatic changes, first and foremost to shed light on the cause of the large ...
-
(Master thesis / Masteroppgave, 2012)Wildfires are a source of major perturbations in the earth-atmosphere system. Between 1997 and 2008, an area of roughly 4 · 106 km2 has been burned each year. Among other species, wildfire aerosols consist of black carbon ...
-
(Master thesis / Masteroppgave, 2009)The heat capacity of the global ocean is very large compared to the rest of the spheres in the climate system of the Earth. It is therefore reasonable to assume that ocean heat uptake or release would manifest itself in ...
-
(Master thesis / Masteroppgave, 2014)The emission of ozone precursors as CO, and NOx has increased over the last decades, this report looks at how this increase potentially could affect the concentration of tropospheric ozone over India. It gives a short ...
-
(Master thesis / Masteroppgave, 2009)Aerosols have in recent years been given increased attention due to their effects on climate and health. Drastic reductions in sulphur emissions in Europe during the last two decades have led to a larger relative importance ...

-
(Master thesis / Masteroppgave, 2018)Air pollution from traffic is a major health problem in urban areas, and there is a great interest in modeling and measuring the dispersion of pollutants from near- ground sources. Due to the complex nature of the motions ...
-
(Master thesis / Masteroppgave, 2010)The growth of the international ship trade has raised the great concern about the impact of the ship emitted pollutants to the clouds and climate, air quality est. Apart from emitting large extents of sulphur dioxide which ...
-
(Master thesis / Masteroppgave, 2009)This thesis presents results from an AGCM sensitivity study in which the response in the Northern Hemisphere storm tracks to an imposed SST anomaly is investigated. The study was motivated by observational studies cited ...

An Investigation of Emissions Sources Contributing to the Deposition of Reactive Nitrogen in ScandinaviaRestricted Access (Master thesis / Masteroppgave, 2019)
-
(Master thesis / Masteroppgave, 2015)The influence of diminishing sea ice and increased aerosol number concentration on low clouds over the Beaufort Sea, north of Canada and Alaska, has been investigated by use of a formulation of the Weather Research and ...
-
(Master thesis / Masteroppgave, 2020)A transition to renewable energy is needed to mitigate climate change. This transition has been led by wind energy, and it is expected to continue to be the largest source of renewable energy through to 2030 (Sawyer et ...
