Urban heat island case –natural hazard mappingUrban heat island case –natural hazard mapping
Urban heat island intensity in summer derived using daytime and nighttime LST averaged over summers of 2002-2010 from Aqua MODIS product with 1km resolution.
Urban heat island case – impact mappingUrban heat island case – impact mapping
Daytime abd nighttime impact maps derived using the number of paramedic interventions per districts in the summers 2009-2012. (Data from Inspectorate for Emergency Situations Vasile Goldis, Arad, Romania.
Urban heat island case – an example of risk mappingUrban heat island case – an example of risk mapping
SEERISK project risk mapping for disaster management community – no new science development but the framework to transfer of science to disaster management community. A risk map is now developed on qualitative base; our scientific aim is to develop a quantitative base for risk assessment of heat waves in urban areas.

quantitative assessments of natural hazards related to climate variability and change;
best quantitative coupling with impact data to quantitatively assess the risks.
