Description

The dataset consists of two shapefiles that provide information on outdoor heat stress and anthropogenic heat flux in Colombo, Sri Lanka in 500 m resolution.

1. "heat_stress_indicator.shp" contains the outdoor heat stress indicators, including heat index (HI), humidex (HD), and discomfort index (DI). These indicators were calculated using the modelled variables of urban land surface model SUEWS, and the values represent the averages at 7:00, 14:00, 19:00, and 23:00 during a heatwave (23-28, 2020) in Colombo, Sri Lanka. The results are for each 500 m grid across Colombo.

2. "QF.shp" contains the calculated anthropogenic heat flux for each 500 m grid in Colombo, Sri Lanka.
