Air temperature in complex urban terrain varies. A large proportion of this variation originates from differences in thermal characteristics of materials that together make up the terrain. While roads and buildings can lead to higher temperatures in urban landscapes, trees and other green urban infrastructure can provide cooling. Hence, depending on the type, make and proportion of urban infrastructure (e.g. grey, green, blue), air temperatures will vary.

Three networks containing a total of 120 local heat loggers (LHL) were deployed in the Penrith local government area between 11 and 13 December 2019. Each LHL recorded near-surface air temperatures at 10 minute intervals until the beginning of April 2020. This generated a total of nearly 1.7 million raw measurements.

This dataset provides measurement locations, physical address, geographic location, and species, height and canopy density of trees at each location. Note, locations are listed according to council area and suburb. Data are individual measurements of air temperature at 10-minute intervals for 113 locations. Mean, maximum and minimum measurements are also provided for each location.
Data Note: Tair (°C) = air temperature measured in degrees Celsius. Data is provided in csv and xlsx formats.

The associated research report includes detailed methodology, analysis of results, and the heat maps generated for each area, as well as conclusions and recommendations.
