In this study ideas from extreme value theory are for the first time applied in the field of stratospheric ozone research, because statistical analysis showed that previously used concepts assuming a Gaussian distribution (e.g. fixed deviations from mean v ...
Tropospheric ozone is a climate relevant greenhouse gas, as well as an atmospheric pollutant. Its abundance in the troposphere is mainly governed by the influx of stratospheric air masses and the photochemical production due to anthropogenic and biogenic o ...
In this study the frequency of days with extreme low (termed ELOs) and extreme high (termed EHOs) total ozone values and their influence on mean values and trends are analyzed for the world's longest total ozone record (Arosa, Switzerland). The results sho ...
As part of the Hemispheric Transport of Air Pollution (HTAP; < a href='http://www.htap.org' target='_blank'> http:// www.htap.org ) project, we analyze results from 15 global and 1 hemispheric chemical transport models and compare these to Clean Air S ...
This work investigates the occurrence frequency of days with high erythemal UV doses at three stations in Switzerland and Austria (Davos, Hoher Sonnblick and Vienna) for the time period 1974-2003. While several earlier studies have reported on increases in ...
Tropospheric ozone (O3) is a harmful pollutant and an increasingly important green-house gas. Tropospheric O3 distributions are determined by complex and non-linear interactions between photochemistry and transport processes. The first objective of this th ...
Current and future dynamics, of environmental legislations and trading market, of the fuel and electricity prices due to the market liberalization or resource shortages, and of the innovations of power/cogeneration technologies, impose great challenges on ...
Mode choice is influenced by quantitative aspects such as cost and time, but importance should be given to qualitative aspects such as people's attitudes or perceptions towards the different modes as well. These latent characteristics can be integrated int ...
A previous report by the present authors [1] clarified the diffuser effect of the draft tube and the effects of swirl in the runner downstream on the hydraulic instabilities in power generation plants. The present study was intended to study the effect of ...

This paper examines the global potential for deployment of fusion power through elaboration of multi-regional long-term electricity market scenarios for the time horizon 2100. The probabilistic simulation dynamic programming model PLANELEC-Pro was applied ...
