2.3.18 Urban heat island effect

Social challenge/ impact linked to:	Environmental
Co-creation phase linked to:	E) Co-monitoring
Level of importance	1 - High Importance / must have
Description	The term urban heat island (UHI) refers to the higher temperatures of cities compared with surrounding areas.
Scale as linked to D2.2 framework	City Neighborhood Project Area
Data source and input type	satellite data for surface temperatures (e.g. The US Landsat5) satellite data for surface temperatures air temperatures
Connection with SDGs	Goal 11: Sustainable cities and communities Goal 13: Climate action
Required Data	A combination of satellite data for surface temperatures and data from monitoring stations or traverses for air temperatures offers the most complete picture of a city's heat island.
Expected Outputs	Urban area that is significantly warmer than its rural or undeveloped surrounding areas. Expressed and evaluated as temperature (°C).
Calculation methods	The Urban heat island temperature effect is calculated as: the daily average global radiation S, the maximum-minimum temperature difference ΔT. the daily average wind speed, measured at 10m above ground.
Level of expertise required	High
