CLARITY Screening Service for Climate Hazards, Impacts and Effects of the Adaptation Options

The CLARITY project (www.clarity-h2020.eu) aims to implement a
new generation of climate services that allow the service users to perform an initial assessment of the expected climate change effects in the project area, as well
as an initial assessment of the need for and of the usability of the adaptation options in the early project planning phase. The target users of this service are the
consultants and urban planning experts that aren’t climate change experts but
need to produce standardized reports indicating the climate hazard, exposure and
impact data, as well as the expected impact of the adaptation options in the project
area, as a part of the project planning. The initial implementation of this service
uses the available open data to calculate the local heat hazard, population exposure and related impact indicators at the project location on the fly. In the initial
implementation, the heat related can be automatically calculated for more than
400 European cities, with a spatial resolution of 500x500m2. Extension to the
flooding hazards and related impacts is in implementation. This article will describe in more detail the workflow and the technical implementation of the
CLARITY screening service and discuss the value, potential and the limitations
of the current service implementation.
