VALUE is an open European collaboration to intercompare downscaling approaches for climate change research, focusing on different validation aspects (marginal, temporal, extremes, spatial, process‐based, etc.). Here we describe the participating methods and first results from experiment, using “perfect” reanalysis (and reanalysis‐driven regional model (RCM)) predictors assess intrinsic performance of precipitation temperatures over a set 86 stations representative main climatic regions in...
Abstract Temperature is a key variable for monitoring global climate change. Here we perform trend analysis of Swiss temperatures from 1959 to 2008, using new 2 × km gridded data‐set based on carefully homogenised ground observations MeteoSwiss. The aim this study twofold: first, discuss the spatial and altitudinal temperature characteristics in detail, second, quantify contribution changes atmospheric circulation local effects these trends. seasonal trends are all positive mostly...
Abstract There is growing awareness among governments, businesses, and the general public of risks arising from changes to our climate on time scales months through decades. Some climatic could be unprecedented in their harmful socioeconomic impacts, while others with adequate forewarning planning offer benefits. therefore a pressing need for decision-makers, including policy-makers, have access use high-quality, accessible, relevant, credible information about past, present, future help...
To make sound decisions in the face of climate change, government agencies, policymakers and private stakeholders require suitable information on local to regional scales. In Switzerland, development change scenarios is strongly linked adaptation strategy Confederation. The current for Switzerland CH2018 - released form six user-oriented products were result an intensive collaboration between academia administration under umbrella National Centre Climate Services (NCCS), accounting user...
Abstract. We describe version 2.0 of the chemistry-climate model (CCM) SOCOL. The new includes fundamental changes transport scheme such as transporting all chemical species individually and applying a family-based correction for mass conservation nitrogen, chlorine bromine groups, revised ozone, furthermore more detailed halogen reaction deposition schemes, cirrus parameterisation in tropical tropopause region. By means these manages to overcome or considerably reduce deficiencies recently...
Abstract Regional projections of future climate with associated uncertainty estimates are increasingly being demanded. Generally, such scenarios rely on a finite number model and accompanied by considerable uncertainties which cannot be fully quantified. Consequently, probabilistic conditioned several subjective assumptions can treated in Bayesian framework. In this study, recently developed multi‐model combination algorithm is applied to regional simulations from the ENSEMBLES project...
Temporal variability is an important feature of climate, comprising systematic variations such as the annual cycle, well residual temporal short‐term variations, spells and from interannual to long‐term trends. The EU‐COST Action VALUE developed a comprehensive framework evaluate downscaling methods. Here we present evaluation perfect predictor experiment for variability. Overall, behaviour different approaches turned out be expected their structure implementation. chosen regional climate...
The application of climate change impact assessment (CCIA) studies in general and especially the linkages between different actor groups typically involved is often not trivial subject to many limitations uncertainties. Disciplinary issues like competing downscaling approaches, imperfect model data uncertainty propagation as well selection appropriate sets are only one part story. Interdisciplinary transdisciplinary challenges add these, provision their usage require at least a minimum...
Abstract Heat exposure constitutes a major threat for European workers, with significant impacts on the workers’ health and productivity. Climate projections over next decades show continuous accelerated warming Europe together longer, more intense frequent heatwaves regional local scales. In this work, we assess increased risk in future occupational heat stress levels using wet bulb globe temperature (WBGT), an index adopted by International Standards Organization as regulatory to measure...
The spatial dependence of meteorological variables is crucial for many impacts, example, droughts, floods, river flows, energy demand, and crop yield. There thus a need to understand how well it represented in downscaling (DS) products. Within the COST Action VALUE, we have conducted comprehensive analysis variability output over 40 different DS methods perfect predictor setup. evaluated against daily precipitation temperature observations period 1979–2008 at 86 sites across Europe 53...
The latest Swiss Climate Scenarios (CH2018), released in November 2018, consist of several datasets derived through various methods that provide robust and relevant information on climate change Switzerland. scenarios build upon the regional model projections for Europe produced internationally coordinated downscaling effort EURO-CORDEX. simulations from EURO-CORDEX at two spatial horizontal resolutions, global models, three different emission scenarios. Even with this unique dataset...
Climate change will result in more intense and frequent weather climate events that continue to cause fatalities, economic damages other adverse societal impacts worldwide. To mitigate these consequences support better informed decisions improved actions responses, many National Meteorological Hydrological Services (NMHSs) are discussing how provide services on as part of their operational routines. The authors outline a risk framework can the development by NMHSs. In addition hazard...

Abstract. As a consequence of current and projected climate change in temperate regions Europe, agricultural pests diseases are expected to occur more frequently possibly extend previously non-affected regions. Given their economic ecological relevance, detailed forecasting tools for various have been developed, which model phenology, depending on actual weather conditions, suggest management decisions that basis. Assessing the future risk pest-related damages requires data at high temporal...
ABSTRACT Ensembles of regional climate models are widely used to obtain change signals and evaluate associated uncertainties over a specific region. These forced by general circulation ( GCMs ) at their lateral boundaries. The most recent multi‐model ensembles projects – ENSEMBLES CORDEX rely on limited set about 10 per greenhouse gas emission scenario. It was shown previously that in particular, RCM temperature responses tend cluster according driving GCM . Therefore, it is important better...
Abstract. Along with the higher demand for bias-corrected data climate impact studies, number of available sets has largely increased in recent years. For instance, Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) constitutes a framework consistently projecting impacts change across affected sectors and spatial scales. These are very attractive any application since they offer worldwide based on global models (GCMs). In complementary way, CORDEX initiative incorporated...
ABSTRACT Climate information provided by global or regional climate models ( RCMs ) are often too coarse and prone to substantial biases for local assessments use in impact models. Hence, statistical downscaling becomes necessary. For the Swiss National Change Initiative CH2011 ), a delta‐change approach was used provide daily scenarios at scale. Here, we analyse Richardson‐type weather generator WG as an alternative method downscale precipitation, minimum maximum temperature. The is...
