The researchers also found that AH decreased more in urban centers and the change in AH varied in terms of urban land use between cities and periods.
“With a much higher spatial resolution, the resulting AH was consistent with the latest global AH dataset, providing ‘objective and refined features of human activities during the pandemic’,” said Prof. Meng.
Although UHI changes during the COVID-19 pandemic cannot be entirely attributed to AH changes, the considerable reduction in AH is an important feature accompanying the weakening of the UHI.
