CLARITY Project team has developed a generic methodology that is appropriate for both expert and screening studies and aligned with the IPCC-AR5 approach. CLARITY methodology consequently applies the risk-based approach to determine climate change impacts, by adopting the well know relation R = H x E x V, where Hazard (H), Exposure (E), and Vulnerability (V) represent the key aleatory variables.
A set of simple ad-hoc “screening” models was developed for use in the screening services. These models are based on open data (e.g. Copernicus, Eurostat), automatically calculated on demand for the project area, and provide relevant data at ~500m resolution for a large number of European metropolitan areas. Following CLARITY “screening” models were developed:
- Hazards: simple microclimate models for Heat Wave and pluvial flooding hazards.
- Exposure: population, several types of traffic infrastructure, buildings, and open areas
- Vulnerability / impact: indicators relating hazards to exposure, such as “excess heat mortality” and “flood damage to buildings”
These models rely on CLARITY algorithms for extracting detailed information from various openly available data sources. These parameters include key parameters related to the urban morphology (terrain, vegetation, building density, etc.) land use (residential, industry, transport network, open spaces, etc.) and surface type (e.g. albedo, emissivity, green fraction, runoff coefficient, etc.).
Finally, a set of adaptation options and adaptation strategies was defined, and the ad-hoc models estimating their effects on local hazard distribution and mitigation of climate change impacts were also implemented. Detailed information on these developments is available in D2.4. “CLARITY Demonstrators Implementation and Validation Report v2” and D3.3 “Science support report v2”.
In addition, the project has developed an online marketplace that facilitates matching the regional offers and demand for climate adaptation know-how, products and services (https://marketplace.myclimateservices.eu/ , D5.7 “MyClimateService.eu Marketplace”) and a set of webinars, video-tutorials and video features explaining various project developments and results in a simple way (
