Deducing hourly data from CH2018 for sustainable building modelling

2020-​2021

The CH2018 Climate Scenarios for Switzerland present projections for climatic changes in Switzerland during the 21st century. The projected changes will also affect the building sector in Switzerland. Building structures are built to last for several decades and the installed heating and cooling systems are typically replaced only once during the lifetime. Hence, projected climate change needs to be considered when planning new buildings today. The aim of this project is to produce single years that represent future mean and extreme climate conditions in Switzerland. These reference years are deduced from CH2018 at hourly resolution and preserving physical consistency between various variables.

PASC ENIAC – Enabling the ICON model on heterogeneous architectures

2017-2021

Recent years have seen an immense progress in our capacity to predict weather and climate evolution using numerical models. An important driver for this development has been the rapid progress in high-performance computing (HPC). It is expected that with the further increase of high-performance computing capacity, the computational resolution of such models will continue to be refined in the next decades. This development offers exciting prospects. From a weather and climate science perspective, increasing model resolution will make it possible to base such models on a set of equations that is much closer to first principles. In particular, at horizontal resolutions of O (1 km), the models become cloud resolving and start to explicitly represent the dynamics of deep convective and thunderstorm clouds without the help of semi-empirical parameterizations. This could enable more sophisticated climate-change scenarios with better guidance for impact assessment and climate change adaptation measures.

CH2018 - Climate Scenarios for Switzerland

2018

The CH2018 Climate Change Scenarios show where and how climate change affects Switzerland and what global climate change mitigation efforts can do about it. The expected consequences of unchecked climate change for Switzerland include more hot days, dry summers, heavy precipitation and winters with little snow. However, global efforts to mitigate climate change could curb future climate change. The CH2018 initiative is one of the focus areas of the external page National Center for Climate Services (NCCS) and involved the partners ETH Zurich, MeteoSwiss, C2SM, and the University of Bern.

Greenhouse gas sources and sinks

2012-2016

Large uncertainties remain with respect to the sources and sinks of greenhouse gases, which play a major role in the climate system and climate change. The sources and sinks of carbon dioxide (CO2) and methane (CH4) are investigated through two projects:

  • 2012-2014: CarboCount CH - Quantifying Greenhouse Gas Fluxes.
