Atmospheric impacts on daytime urban heat island [PDF]

open access: yes, 2018
Daytime urban heat island effects can be weak compared to night time and even reversed (as in the case of cool islands, where urban locations display lower temperatures than at a rural site), mostly due to shading effects from buildings, vegetation, and ...
