Are you interested in how to mitigate hyper-local urban heat exposure?
Debate of the article titled More than surface temperature: Mitigating exposure in hyper-local land system from 2022, by V. Kelly Turner, Morgan L. Rogers, Yujia Zhang, Ariane Middel, Florian A. Schneider, Jonathan P. Ocón, Megs Seeley, and John Dialesandro, published in the Journal of Land Use Science.
This is a great preparation to our next interview with V. Kelly Turner in episode 472 talking about how urban heat is more than just a surface temperature measured from a distance.
Since we are investigating the future of cities, I thought it would be interesting to see how useful remote sensing of land surface temperature really is for urban planning at hyper-local scales. This article argues that conventional remote sensing is inadequate for guiding heat adaptation because it overlooks the critical role of solar radiation and local geometry.

Abstract: Regional land surface temperature (LST) maps derived from remote sensing data are most available to cities to assess and respond to heat. Yet, LST only captures one dimension of urban climate. This study investigates the extent to which remote sensing derived estimates of LST are a proxy for multiple climate variables at hyper-local scales (<10s of meters). We compare remotely sensed estimates of LST (RS-LST) to field and simulated LST, MRT, and air temperature (AT), in a neighborhood in Tucson, Arizona, USA. We find that LST, MRT, and ST follow different diurnal trends masked by RS-LST. We also find that three-dimensional urban design is a better predictor of MRT than two-dimensional land cover and albedo – a known determinant of RS-LST. Shade is a better predictor of both simulated LST and MRT than RS-LST. We conclude that RS-LST is not adequate for guiding heat mitigation at hyper-local scales in cities.
