Climate DiagnosticsWorking with users on recent climate variability and trends, towards producing climate products, filling decadal gap with RCM runs
Start with recent past climate using high resolution Eobs for Europe, ENSEMBLES RCM runs for Europe
Need capture real variability – do these runs SRES GCM-RCM runshave even average variability?
Should we even ask that question of GCM-RCM runs?
How do we use RCM to fill decadal gap?
RCMs with s2d initial condition ensembles?

Caminade et al, 2010 (in review)
Rift Valley Fever risk (%) based on rainfall from ERAINTERIM reanalysis (1990-2007). The number of RVF risk events is defined by a dry spell (10 consecutive days with total rainfall below 1mm) followed by a convective event (high precipitation defined by one or two days following the dry spell above the 90th percentile) occurring during the late rainy season (SON). The total number of RVF risk events is then rescaled to range between 0 and 100% to define the risk. The dotted, crossed and filled black areas depict animal host densities (cattle + buffalo + sheep + goats) above 1, 10 and 100 per km2 (FAO, 2005).

Climate Services Agenda - a seamless one?• Who is doing what, where and with whom e.g. can we share good practise and/or join forces?
• Are Met Services interacting as much as possible with other researchers working on impacts and data use?
• Who is thinking seamlessly across multiple timescales?
• Who is developing this seamlessness with the user community?
• How can WGSIP, CLIVAR, WCRP help connect this Agenda with the impacts community?
Introduction, Methods and Results, Discussion
Summary to seamlessness• Grand ensemble approach – combined ensembles from different systems –
bound uncertainty, maximise skill, model climates
• Impacts model portability – develop models work different climate streams and grand ensemble – impact uncertainty, integrated model value
• Field and Environmental Observations – verification and dynamic insight
• Model data post processing – downscaling, bias correction, dressing
• Continuity to society – decision makers, product tailoring, decision support systems, understanding critical uncertainty and thresholds, agent based models, combination with remote sensing and observations, through to policy and project impact on society

Introduction
Improving the use of climate prediction by quantifying, understanding and managing uncertainty.
Through working with stakeholders, the EQUIP team will develop new methodologies and analyses for using climate information that will be employed by decision makers in a set of case studies.
We will quantify and understand the uncertainty surrounding future droughts, heatwaves, crop production and marine ecosystems.
