Temporal and spatial analysis of ozone concentrations in Europe based on timescale decomposition and a multi-clustering approach

Satoshi Takahama, Eirini Boleti, Christoph Hueglin

Air quality measures that were implemented in Europe in the 1990s resulted in reductions of ozone precursor concentrations. In this study, the effect of these reductions on ozone is investigated by analyzing surface measurements of this pollutant for the t ...

Statistical methods for accounting and understanding ozone trends derived from observations

Eirini Boleti

Emissions of ozone precursors have been regulated in Europe since around 1990 with air quality control measures, which resulted in reductions of nitrogen oxides and volatile organic compounds concentrations. In order to understand how these measures have a ...

Effect of Indoor Temperature and Glazing with Saturated Color on Visual Perception of Daylight

Marilyne Andersen, Jan Wienold, Giorgia Chinazzo

This paper presents the combined effect of indoor temperature (19 degrees C, 22 degrees C, and 26 degrees C) and colored glazing (blue, orange, and neutral) on visual perception of daylight. Experiments were performed in an office-like test room, in which ...

Seasonality in cholera dynamics: A rainfall-driven model explains the wide range of patterns in endemic areas

Enrico Bertuzzo, Theo Baracchini

Seasonal patterns in cholera dynamics exhibit pronounced variability across geographical regions, showing single or multiple peaks at different times of the year. Although multiple hypotheses related to local climate variables have been proposed, an unders ...

The temporal patterns of disease severity and prevalence in schistosomiasis

Andrea Rinaldo, Lorenzo Mari, Marino Gatto

Schistosomiasis is one of the most widespread public health problems in the world. In this work, we introduce an eco-epidemiological model for its transmission and dynamics with the purpose of explaining both intra-and inter-annual fluctuations of disease ...

Seasonal and diurnal cycles of liquid water in snow—Measurements and modeling

Nander Wever

Evaluating and improving snow models and outflow predictions for hydrological applications is hindered by the lack of continuous data on bulk volumetric liquid water content (θw) and storage capacity of the melting snowpack. The combination of upward looki ...

Génération multi-sites de variables météorologiques horaires en zone alpine : application à la simulation de scénarios de crues du Rhône supérieur suisse

Abdelkader Mezghani

Water resources management and hydrological risks are based, to a large extent, on our competence to generate relevant hydrological scenarios under present and future climatic situations. In alpine areas, characterized by highly complex topography, the ava ...

Mid- to late Holocene climate change- an overview

Jed Oliver Kaplan, Stefan Müller

The last 6000 years are of particular interest to the understanding of the Earth System because the boundary conditions of the climate system did not change dramatically (in comparison to larger glacial–interglacial changes), and because abundant, detailed ...

Comparing effects of oligotrophication and upstream hydropower dams on plankton and productivity in perialpine lakes

Alfred Johny Wüest, Martin Schmid

In recent decades, many perialpine lakes have been affected by oligotrophication due to efficient sewage treatment and by altered water turbidity due to upstream hydropower operations. Such simultaneous environmental changes often lead to public debate on ...

Multimodel ensemble simulations of tropospheric NO2 compared with GOME retrievals for the year 2000

Isabelle Bey, Jérôme Drevet

We present a systematic comparison of tropospheric NO2 from 17 global atmospheric chemistry models with three state-of-the-art retrievals from the Global Ozone Monitoring Experiment (GOME) for the year 2000. The models used constant anthropogenic emissions ...

Long-Range Transport to Europe : Seasonal Variations and Implications for the European Ozone Budget

Isabelle Bey, Marion Auvray

We use a chemical transport model (GEOS-CHEM) to quantify the contribution of long-range transported pollution to the European ozone ({O}{3}) budget for the year 1997. The model reproduces the main features observed over Europe for {O}{3}, carbon monoxid ...
