While that would work as an estimate of total sq meters, applying that scale in a localized area would have too much of an impact on wind/currents, inversion, and the downstream of those changes.

First targets would be urban heat islands and airports. Second would be industrial and manufacturing facilities. Regulations and Nimby would likely mean manufacturing and industrial would be more quick to adapt for use.

The case for urban heat islands is pretty straightforward, but the application with airports would be to mitigate the heat trapping that takes place, especially overnight. Exhaust from flights result in more heat being trapped, similar to urban heat island but due to atmospheric effects and not solely due to surface materials and lack of greenspace.

Imagine a checkerboard of huge tiles dropping the temperature across a large area of desert, for a desert reclamation project.

Seems we are going to have to geoengineer in the future, greening deserts would be a silver lining to all the climate and response chaos.
