Extreme precipitation and their impact on local planning in Sweden - a tool for climate adaptation planning
Knowledge about future characteristics of precipitation climate and extremes is of vital importance for, last but not least, municipal planning. A high number of GCM simulations is available giving information on very coarse spatial scales. In order to enable future planning of climate adaptation strategies, the municipalities need to know in more detail how climate might be change in their domain. Regional differences can be significant and too coarse GCM simulation don't give sufficient information on that scale.
Objective: GCM simulation have been downscaled to station level usin g a stochastic weather generator. Depending on the number of stations used (241 having data 1961-2004 so far), this yields a much more detailed picture compared to plain GCM scenarios and provide a useful planning background. This study is the continuation of a former project and the main objective is to develop an easy to use tool visualizing the interpolated results.

Potential impact of climate trends and weather extremes on outdoor thermal comfort in European cities - implications for sustainable urban design? 2010
The mean air temperature in Europe is expected to rise 2 to 6°C by 2100. This means that winters will be milder and summers hotter, with an intensification of extreme heat waves in summer. The WHO acknowledges that the future increase in temperature will have profound effects on the health and well-being of urban citizens. In order to mitigate the problems with intensified heat stress and design sustainable cities quantitative information on factors determining outdoor thermal comfort is required.
The main objective of this interdisciplinary and transnational research project is study the potential impact of climate trends and extreme weather events (heat waves and cold spells) on outdoor thermal comfort in urban areas in order to develop a set of design guidelines and policies on how maintain health and thermal comfort under changed climate conditions and extreme weather events for European cities.

Have atmospheric-circulation changes reduced the NO2 concentrations from local emission sources in Gothenburg? 2010
NO2 is one of the most prominent air pollutants produced by modern transport infrastructures. The majority of NO2 in Gothenburg is thought to originate from local transport burning fossil fuels, but atmospheric conditions play an important role in determining the actual concentrations.
In collaboration with the Swedish Environmental Research Institute IVL, the Regional Climate Group has been investigating how regional atmospheric conditions affect NO2 concentrations in Gothenburg. Computer simulations can be used to estimate how much air pollution is caused by local emissions, and how much comes from long-distance transport. These simulations suggest that the component of the air pollutant NO2 in Gothenburg caused by local emissions has decreased in between 1999-2008. We hypothesize that the decrease was caused by changes in atmospheric pressure and wind patterns, and we are investigating these changes using historical temperature, geostrophic wind and pressure data.
The work is supported by the Center for Environment and Sustainability (GMV), the Swedish Environmental Research Institute IVL, and the Regional Climate Group at GU.
The Greater Baltic Area Paleoclimate Database (BALPAL). 2009
Background: A new climate database is under construction at the Department of Earth Sciences at the University of Gothenburg: The Greater Baltic Area Paleoclimate Database.
Hans Linderholm, professor of physical geography and his team will together create a database to share their data sets with other researchers. It is hoped that other researchers
will also contribute their data, and so the project can build a comprehensive, high-quality database with data from paleoclimate ressearch throughout northwestern Europe.
Knowledge about past climate conditions has the potential to provide a deeper understanding of today's climate, both in terms of natural climate variability and human impact on climate.
Funding: The project is funded by Vetenskapsrådet (the Swedish Research Council, VR), 2009-2010.
Effect of Intensive Forestry on greenhouse emissions from Swedish forests. 2008
Background: Swedish forests act as large carbon sinks. But what will happen in the future if forest managers start applying nitrogen fertilizers to grow biofuel? Nitrous oxide (N2O) is 296 times more potent as a green house gas than carbon dioxide, and it stays in the atmosphere for 120 years. Tellus scientists from the University of Gothenburg are participating in a new research project that aims to find out.
According to IPCC, anthropogenic N2O emission should be reduced by 50%. But very little is known about NO and N2O emissions from fertilised young forests, so firstly this needs to be studied more thoroughly. The project will then investigate net emissions resulting from different forestry fertilization strategies. This means looking not only at sequestration (in trees, soil, and wood products), but also carbon emissions from forest operations, avoided emissions due to wood product substitution of fossil fuels and non-wood products, and of course the emission of non-carbon GHGs like N2O. The overall aim i a holistic overview of how intensive forestry can contribute to a positive climate effect through decreased net GHG emission in Sweden.
Methods: The project will use the CoupModel to simulate how forests grow - and their greenhouse emissions - depending on the soil, the available nutrients, and the climate. Because the project will take a long-term view, looking at emissions over the next 100 years, this means the simulations must incorporate climate change. The Regional Climate Group at the University of Gothenburg are contributing downscaled climate change scenarios that can be used for the simulations.
Participants: The project is a joint collaboration between SLU (Johan Bergh), Mid Sweden University (Leif Gustavsson) and Gothenburg University (Leif Klemedtsson). The climate modelling will be linked to the GU Tellus platform, and is begin conducted by David Rayner under the supervision of Prof. D. Chen, and done in co-operation with the Rossby centre.
IRWIN - Improved local road winter index to assess maintenance needs and adaptation costs in climate change scenarios. 2008
Background: Roads become slippery and dangerous when temperatures are close to zero, and salting is a winter maintenance activity that can help. Should road owners expect to perform more salting under climate change conditions? What about snow ploughing - climate change scenarios show more winter precipitation in Sweden. A new project involving the Regional Climate Group at the University of Gothenburg is investigating.
Improved tools for road owners are urgently needed to help them cope with rapidly progressing climate change. Scenarios with good spatial and temporal resolution that show the climate we might expect in the future, especially regarding severe weather events, are a very important tool for planning activities. Traditionally, downscaled climate change scenarios are calculated using ordinary meteorological data. But meteorological station data is not the most appropriate data for describing road climate conditions.
Methods: The idea of IRWIN is to combine the best climate change scenarios from Global Climate Models (GCMs) with data from field stations from the Road Weather Information systems (RWIS) used by many countries. These stations are located along important road networks, and provide accurate information about road climate. The goal of IRWIN is to use this new dataset to develop an improved winter road index which can be used to assess the costs and benefits of various winter maintenance strategies.
Participants: The IRWIN project participants and their representatives are Foreca Consulting Ltd, Finland (Pirkko Saarikivi), Klimator AB, Sweden (Torbjörn Gustavsson) and Department of Earth Sciences, University of Gothenburg, Sweden (Dave Rayner).
Funding: IRWIN is funded as a joint research project through "ERA-NET ROAD - Coordination and Implementation of Road Research in Europe", a Coordination Action funded by the 6th Framework Programme of the EC.
