URBAN HEAT VULNERABILITY MAP OF LIMERICK, IRELAND

Indicator Description
Urban Heat Vulnerability Index: This indicator shows the most vulnerable areas to extreme heat event such as heat waves and also the urban heat island effect. It is calculated by using the framework of evaluation of vulnerability to climate change impacts which has been recommended by the Intergovernmental Panel on Climate Change (IPCC). This framework contains that vulnerability is a funcitno of exposure, sensitivity and adaptive capacity of a given system to climate change impacts. In this case, the given system is the urban environment in the city of Limerick. The exposure, sensitivity and adaptive capacity have been obtained from the indicators listed below.
Surface Temperature - Landsat 8: This indicator indicates the maximum At-Satellite Brightness Temperatures obtained from Landsat 8 satellite. Temperatures area given in degree celcius
Vulnerable Population Density Index: This indicator indicates the density of population which are considered to be most vulnerable to extreme heat events. The two age-groups which are considered to be most vulnerable are "0 - 15" and "60 and above". The data source of this index has been obtained from open dataset available in https://data.gov.ie
Water Index (NDWI) - Sentinel 2: This indicator indicates the water bodies from the Normalized Difference Water Index (NDWI) obtained from Sentinel 2 satellite.
Vegetation Index (EVI) - Sentinel 2: This indicator indicates the vegetation concentration from the Enhanced Vegetation Index (EVI) obtained from Sentinel 2 satellite.
