Abstract
Abstract. The adverse impacts of urban heat and global climate change are leading
policymakers to consider green and blue infrastructure (GBI) for heat
mitigation benefits. Though many models exist to evaluate the cooling impacts
of GBI, their complexity and computational demand leaves most of them largely
inaccessible to those without specialist expertise and computing facilities.
Here a new model called The Air-temperature Response to
Green/blue-infrastructure Evaluation Tool (TARGET) is presented. TARGET
is designed to be efficient and easy to use, with fewer user-defined
parameters and less model input data required than other urban climate
models. TARGET can be used to model average street-level air temperature at
canyon-to-block scales (e.g. 100 m resolution), meaning it can be used to
assess temperature impacts of suburb-to-city-scale GBI proposals. The model
aims to balance realistic representation of physical processes and
computation efficiency. An evaluation against two different datasets shows
that TARGET can reproduce the magnitude and patterns of both air temperature
and surface temperature within suburban environments. To demonstrate the
utility of the model for planners and policymakers, the results from two
precinct-scale heat mitigation scenarios are presented. TARGET is available
to the public, and ongoing development, including a graphical user interface,
is planned for future work.
