CLARIS strategic objectives
1) To set up and favor the technical transfer and expertise in Earth System and Regional Climate Modeling between Europe and South America together with the providing of a list of climate data (observed and simulated) required for model validations.
3) To strengthen the communication between climate researchers and stakeholders, and to demonstrate the feasibility of using climate information in the decision-making process.
2) To facilitate the exchange of observed and simulated climate data between the climate research groups and to create a South American high-quality climate database for studies in extreme events and long-term climate trends.
NCT1: Project coordinationWP1.1: CLARIS and the European Commission (J-P Boulanger, CNRS)WP1.2: CLARIS communication and dissemination activities (J.-P. Boulanger, CNRS, and Carlos Ereño,

CLARIS WP 4.2: Climate andvector-borne epidemics
Nicolas Degallier (IRD)(CNRS, CONICET, INPE, USP, INGV, UR, UCH, MPI)
Create an epidemiological relational database including high-quality detailed data on Yellow Fever (YF) cases (human and monkeys) and Dengue human cases in Brazil to be accessed on the CLARIS web site.
Determine which climate parameters are key ones in explaining the spatial and temporal distribution of YF and Dengue cases.
Generate epidemiological scenarios (Dengue transmission, level of immune status, vector densities and control activities), according to various climate change scenarios.
CLARIS WP 4.2 Deliverables
D4.7 (month 12): Internet-based epidemiological database for YF and Dengue cases in Brazil.
D4.8 (month 24): Report on Dengue-mosquito model analysis and validation, and YF spatio-temporal analysis of cases.
D4.9 (month 36): Maps of Dengue risk evolution for different climate change scenarios and risk assessment indices for YF vaccination decision-making and Dengue integrated control

CLARIS WP 4.2 Tasks
Task 1: o compare various existing Aedes aegypti - Dengue models.
Task 2: to couple the chosen mosquito-Dengue model to a temporal-evolution epidemics model already developed and applied with success in simulating Dengue epidemics.
Task 3: to diagnose the climate impact on simulated past epidemics and to suggest a potential evolution of the regions at risk (Dengue) for different climate change scenarios.
Task 4: to propose to Brazilian Ministry of Health (FUNASA) a risk index for decision-making during vaccination campaigns (Yellow Fever) or vector control (Dengue) based on seasonal climate predictions.
