Workshop: Regional climate model data for climate impact research

4th to 6th February 2013

Have a look at the workshop webpage to download the presentations and material used in the hands-on sessions.

Welcome to the Center for Climate Systems Modeling (C2SM). C2SM is a research center based at ETH Zurich. It is a joint initiative between ETH Zurich, MeteoSwiss, Empa, WSL, and Agroscope with the main objective to improve the understanding of the Earth’s climate system, and our capability to predict weather and climate.

Highlights

PASC14 visualization award for COSMO-1 animation

23 September 2014 - A collaborative effort between C2SM associated scientists at ETHZ (Oliver Stebler, Urs Beyerle and Reto Knutti) and at MeteoSwiss (Oliver Fuhrer and Reto Stöckli) has resulted in a very impressive visualization of a high-resolution (1.1 km, 2 min) simulation produced by the experimental weather model COSMO-1 that is currently developed at MeteoSwiss. This visualization was nominated as the second best visualization presented at the recent The Platform for Advanced Scientific Computing (PASC) Conference.

"Natural variability, radiative forcing and climate response in the recent hiatus reconciled"

18 August 2014 - There is little evidence for a systematic overestimation of the temperature response to increasing atmospheric CO2 concentrations in a large number of climate models (CMIP5 ensemble). This conclusion by Markus Huber and and C2SM member Reto Knutti was published in recent study in "Nature Geoscience" that looked for explanations why global mean surface warming over the past 15 years has been less than in earlier decades and than simulated by most climate models. The authors found that internal variability (El Niño/Southern Oscillation, ENSO) and updated solar and stratospheric aerosol forcings from observations can explain the cooling. An adjusted climate model of reduced complexity was shown to be consistent with the temperature record of the past 15 years. Read the complete study here and see the article in ETH-News (in German).

C2SM members participate in two new Sinergia projects

24 July 2014 - Two Sinergia projects funded by the Swiss National Science Foundation were recently awarded to teams that include members of C2SM including Ulrike Lohmann , Christoph Schär and Heini Wernli. The goal of the project „Cloud-resolving climate modeling on future supercomputing platforms” (crClim) is to develop and exploit a European-scale climate model that is capable to resolve convection at a grid-spacing of 2 km. This endeavor needs close collaboration between atmospheric, climate and computer sciences from ETH, MeteoSwiss and the Swiss National Super Computing Center CSCS. The project “Paleo Fires” has the overall objective to advance the understanding of linkages between climate, land use, fire and vegetation. Participants from ETH IAC, PSI and the University of Berne want to focus on different regions over the most recent period of the last 150 years in comparison to the previous 2000 years.

Modeling energy supply with concentrating solar power

23 June 2014 - Concentrating solar power (CSP) could supply a substantial amount of current energy demand. C2SM member Anthony Patt and two colleagues from the Department of Environmental Systems Science significantly contributed to a study recently published in the journal Nature Climate Change. In the Mediterranean region, for example, the study shows that a connected CSP system could provide 70-80% of current electricity demand, at no extra cost compared to gas-fired power plants. That percentage is similar to what a standard energy production plant, such as a nuclear plant, can provide. In the new study, the researchers simulated the construction and operation of CSP systems, taking into account weather variations, plant locations, electricity demand, and costs.

Public lecture on "The Recent Global Warming Hiatus"

17 June 2014 - The “Latsis Symposium on Atmosphere and Climate Dynamics” takes place in Zurich this week. C2SM supports the meeting of leading scientists from around the world that discuss current questions from cloud microphysics to global circulation. On Friday evening, June 20, Dennis Hartmann (University of Washington) will give a public lecture on “The Recent Global Warming Hiatus: What Does It Mean for the Future?” The rapid rate of global warming since about 1980 has slowed down in the past decade or so, despite the fact that greenhouse gases continue to increase at an accelerated rate. The reasons for this slowdown in warming will be examined and their implications for the future of climate will be explored. The lecture at 18:00 is open to everyone at Auditorium Maximum, ETH Main Building. Admission is free.

"Klimarunde 2013" featured in the annual report of ETH

1 May 2014 - "ETH-Klimarunde" was prominently mentioned in the annual report 2013 of ETH. It states that "imparting knowledge and maintaining a dialogue with society, industry and politics is important to ETH Zurich." "ETH-Klimarunde" was one of the events in 2013 that offered scientists the opportunity to present their work for the UN climate report and discuss it with the public, the annual report says. Read the full report here. More information about "Klimarunde 2013". Register here for "Klimarunde 2014: Innovationen fürs Klima – Was braucht es, damit wir handeln können?"

Spatially explicit inventory of methane fluxes in Switzerland

23 April 2014 - Methane is an important greenhouse gas. Rebecca Hiller, C2SM members Nina Buchmann, Dominik Brunner and co-authors recently published the first high-resolution (500 m × 500 m) gridded methane (CH4) emission inventory for Switzerland. It integrates 90 % of the national emission totals reported to the United Nations Framework Convention on Climate Change (UNFCCC) and recent CH4 flux studies conducted by research groups across Switzerland. In addition to anthropogenic emissions, we also include natural and semi-natural CH4 fluxes, i.e., emissions from lakes and reservoirs, wetlands, wild animals as well as uptake by forest soils. In Switzerland, the highest CH4 emissions in 2011 originated from the agricultural sector (150 Gg CH4 yr−1) were mainly produced by ruminants and manure management. They were followed by emissions from waste management (15 Gg CH4 yr−1) mainly from landfills and the energy sector (12 Gg CH4 yr−1), which was dominated by emissions from natural gas distribution. Compared with the anthropogenic sources, emissions from natural and semi-natural sources were relatively small (6 Gg CH4 yr−1), making up only 3 % of the total emissions in Switzerland. This new inventory will provide valuable input for regional-scale atmospheric modeling and inverse source estimation.
