Reducing Aerosol Forcing Uncertainty by Combining Models With Satellite and Within-The-Atmosphere Observations: A Three-Way Street

Athanasios Nenes

Aerosol forcing uncertainty represents the largest climate forcing uncertainty overall. Its magnitude has remained virtually undiminished over the past 20 years despite considerable advances in understanding most of the key contributing elements. Recent wo ...

Addressing impact of climate change on wind and solar energy infrastructures: the case of India

Yasmine Zakari

In the first part of this thesis, the comparison of two families of CORDEX suggests the improved performance of the latest version in reproducing the local climate. The results indicate increasing future trends for annual wind speeds in the north-west (+0. ...

Socio-technical modeling of smart energy systems: a co-simulation design for domestic energy demand

Claudia Rebeca Binder Signer, Matteo Barsanti

To tackle the climate crisis, the European energy strategy relies on consumers taking ownership of the energy transition, accelerating decarbonisation through investments in low-carbon technologies and ensuring system stability and reliability by actively ...

Limestone Calcined Clay Cements (LC3)

Karen Scrivener, Franco Alberto Zunino Sommariva

The climate emergency requires the adoption of strategies and technologies that effectively reduce CO2 emissions in the short to midterm to keep the global temperature rise below 2 degrees C above pre-industrial levels. Concrete is the substance most consu ...

How building energy models take the local climate into account in an urban context – A review

Dasaraden Mauree

The urban context is often simplified or neglected in Building Energy Models (BEMs) due to the difficulties of taking accurately into account all the heat fluxes emanating from the environment. Oversimplifying the urban context can impact the accuracy of t ...

Quantifying the effects of land use and climate on Holocene vegetation in Europe

Jed Oliver Kaplan

Early agriculture can be detected in palaeovegetation records, but quantification of the relative importance of climate and land use in influencing regional vegetation composition since the onset of agriculture is a topic that is rarely addressed. We prese ...

Neighbourhood morphology and solar irradiance in relation to urban climate

Jean-Louis Scartezzini, Nahid Mohajeri Pour Rayeni, Dan Assouline, Govinda Upadhyay

Assessing the relationship between neighbourhood morphology and urban climate is becoming increasingly important as cities continue to grow and the climate continues to change. Here we focus on the impact of (1) shapes and sizes of buildings, (2) street la ...

Climate responsive strategies of traditional dwellings located in an ancient village in hot summer and cold winter region of China

Jean-Louis Scartezzini, Vahid Moussavi Nik, Shaoqing Gou

Global warming and energy shortage have aroused a great interest in climate responsive strategies of vernacular dwellings during recent years. This study focuses on a qualitative analysis of ancient dwellings located in the village of Xinye, in the hot sum ...

The Political Economy of Climate Policy : Business Interest and Influence on the Swiss CO2 Law

Alexandra Quandt

The topic of the here presented work is the influence of firms on climate policy. This thesis analyses the impact of firms’ influence on the acceptance of climate policy, its effectiveness, and implementation. Hereby, the mediation of private interest is u ...

Spatial modelling of extreme snow depth

Anthony Christopher Davison, Juliette Ferial Blanchet

The spatial modelling of extreme snow is important for adequate risk management in Alpine and high altitude countries. A natural approach to such modelling is through the theory of max-stable processes, an infinite-dimensional extension of multivariate ext ...

Relationships between Local Climate and Hydrology in Sphagnum Mire: Implications for Palaeohydrological Studies and Ecosystem Management

We investigated: a) the hydrology of a small Sphagnum mire located in a transitional climate in Eastern Europe, and b) the relationships between the local climate and hydrology of the mire. We hypothesized that temperature is the most important factor dete ...

Lake Baikal deepwater renewal mystery solved

Alfred Johny Wüest

Deepwater renewal by intrusions and turbulent diffusion in Lake Baikal is very effective despite the enormous depth of up to 1642 m and the permanently stable stratification below similar to 300 m depth. Temperature time series recorded at the bottom of a ...

Generation of meteorological scenarios from NCEP reanalyses. Application for the generation of flood scenarios for the Rhone upstream to Lake Leman

Abdelkader Mezghani

Optimal water resources management requires hydrological scenarios for the climate situation under consideration. These scenarios may be produced from meteorological scenarios thanks to an appropriate hydrological model. The Laboratory "Hydrology and Land ...
