The Baltic Sea marine system - human impact and natural variations
(2010-09-07)The environmental state of the Baltic Sea system is influenced by both natural and anthropogenic factors. Water exchange with the adjacent ocean and within the system depend on large-scale atmospheric circulation and ... -
The Carbon Dioxide System in the Baltic Sea Surface Waters
(2011-05-26)The concentration of carbon dioxide (CO2) in the atmosphere is steadily increasing because of human activities such as fossil fuel burning. To understand how this is affecting the planet, several pieces of knowledge of the ... -
The Mesoproterozoic Hallandian event - a region-scale orogenic event in the Fennoscandian Shield
(2011-05-19)The Sveconorwegian Province occupies the southwestern part of the Fennoscandian Shield. The easternmost tectonic unit of the Province is the 1710-1660 Ma parautochthonous Eastern Segment, which bears the imprint of at least ... -
The Nitrogen Cycle in Soil – Climate Impact and Methodological Challenges in Natural Ecosystems
(2018-08-31)Nitrogen (N) is a fundamental element for life, and limiting in many terrestrial ecosystems. In non-N-fertilized ecosystems, the N inputs can be low, and the nutrient availability for plants is determined by the internal ... -
Towards an improved understanding of precipitation variations over the Tibetan Plateau
(2023-05-09)The Tibetan Plateau (TP) and surrounding regions are known as the ``Third Pole'' because of their polar-like environment and large reservoirs of fresh water. Due to the latter aspect, the TP is also considered the ``Water ... -
Towards prediction in ungauged aquifers – methods for comparative regional analysis
(2020-05-12)Hydrogeological investigations and in particular groundwater resource assessments are strongly reliant on understanding the factors controlling groundwater level dynamics. However, historical records of measured groundwater ... -
Tree rings and climate in Scandinavia and Southern Patagonia
(2017-11-30)The present knowledge of temperature variability during the past millennium has been greatly improved due to an increasing availability of reconstructions made based on paleoclimate proxies, such as tree-rings. These ... -
Tree-rings and climate - Standardization, proxy-development, and Fennoscandian summer temperature history
(2014-05-15)Instrumental meteorological observation are too short for trying to estimate climate change and variability on multi-decadal and centennial time-scales, and when trying to evaluate the response of the climate system to ... -
Trophic interactions in the tundra: Impacts of large mammal herbivory on carbon processes and fungal communities
(2023-12-11)Plant productivity is generally increasing in the Arctic as a consequence of accelerated climate change. The change in plant communities may coincide with a loss of carbon from Arctic soils due to increased decomposition ... -
Tropical cyclone induced extreme wind, rainfall, and floods in the Mekong River Basin
(2020-04-27)Increasing magnitude and frequency of climate extremes under global warming are threatening the socioeconomic development in many parts of the world. The Mekong River Basin (MRB) is a good example for how climate extremes ... -
The Tropospheric Aerosol - Measurements and Modelling. Case studies in Tanzania and Southeast Asia and development of models for size resolved aerosol simulations on the regional scale.
(2009-10-01)The tropospheric aerosol is a complex constituent of the atmosphere that has impacts on health and the climate. This thesis presents five different studies from Tanzania, Southeast Asia and Europe dealing with urban ... -
Urban Climate and Air Pollution in Ouagadougou, Burkina Faso
(2011-05-05)ABSTRACT Africa has recently been singled out by UN Habitat as the fastest urbanizing continent in the world. The most extreme case was found in the Sahelian city of Ouagadougou, Burkina Faso, where the population is ... -
Winter Road Conditions and Traffic Accidents in Sweden and UK - Present and Future Climate Scenarios
(2010-02-04)This thesis investigates the distribution of slippery roads in Sweden and the UK for the present climate and how this may be affected by climate change for the rest of the century. It also addresses future scenarios for ...
