Swiss Climate Change Scenarios CH2011¶
Note
This dataset is from the year 2011. If you are looking for more recent versions of the Swiss Climate Change Scenarios, please refer to the official websites for CH2018 or CH2025 .
The Swiss Climate Change Scenarios CH2011 data provides an assessment of how temperature and precipitation may change over the 21st century in Switzerland. The dataset consists of three parts.
Climate scenarios of seasonal means¶
Climate change scenarios of seasonal mean temperature and precipitation calculated for four seasons, three regions, three scenario periods and three greenhouse gas emission scenarios.
The dataset provides lower, medium and upper estimates of changes in temperature and precipitation relative to the reference period 1980-2009 for three scenario periods (2020-2049, 2045-2074, 2070-2099) and the A1B, A2 and RCP3PD emission scenarios.
Regional scenarios at daily resolution based on probabilistic method¶
Daily scenarios derived from the CH2011 climate scenarios of seasonal means. For each region, each scenario period and each emission scenario, the four seasonal mean changes of the individual projection estimates were transformed into a continuous annual cycle.
The dataset provides lower, medium and upper estimates of changes in temperature and precipitation relative to the reference period 1980-2009 for three scenario periods (2020-2049, 2045-2074, 2070-2099) and the A1B, A2 and RCP3PD emission scenarios.
Local scenarios at daily resolution based on individual model chains¶
Daily scenarios of temperature and precipitation changes at MeteoSwiss observational station sites for each day of the year, for the three scenario periods and ten individual GCM-RCM model chains. Only the A1B emission scenario is covered.
The dataset provides changes relative to the reference period 1980-2009 for three scenario periods (2021-2050, 2045-2074, 2070-2099) and 10 GCM-RCM model chains at 188 (temperature) and 565 (precipitation) stations in Switzerland.
