Urban land cover types influence the urban microclimates. However, recent work indicates magnitude of cover's microclimate is affected by aridity. Moreover, this variation in cooling and warming potentials can substantially alter exposure areas to extreme heat. Our goal understand both relative influences on local air temperature, as well how these vary during periods To do so we apply predictive machine learning models an extensive in-situ 1 m dataset across eight U.S. cities spanning a wide aridity gradient typical heat conditions. We demonstrate tree canopy buildings linearly scales with regional aridity, while turf impervious surfaces does not. These interactions lead consistently mitigate temperature increases arid cities, humid regions varied, suggesting that mitigation possible, but also aggravate or have no significant effect.

Abstract Golf courses are increasingly affected by water scarcity and climate change. An understanding of spatial variability actual evapotranspiration (ET a ) turfgrass quality (TQ) site‐specific management zones (SSMZ) is important for the implementation precision management. Therefore, main objectives this study were to quantify relationship between remotely sensed TQ ET estimates evaluate variations at golf course in Utah. Ground‐based normalized difference vegetation index was collected using TCM‐500 sensor, aerial multispectral thermal imagery data acquired from unpiloted aircraft systems (UAS) 2021, 2022, 2023. A remote sensing TQ‐random forest (RF) model developed six datasets UAS spectral indices RF algorithm. The analyzed determine correlation estimates. SSMZ created integrated with irrigation heads on Thiessen polygons tool. Results demonstrated that TQ‐RF accurate within root mean square error 0.05. stronger fairways ( R 2 = 0.74), tees 0.66), roughs 0.75) as compared greens 0.25) driving range 0.36) July 20, 2022. Actual SSMZ, combination useful scheduling, addressing question how much where irrigate. This demonstrates ability identify variation purpose landscape semi‐arid areas.

Adapting to changes in water availability is becoming an increasingly important environmental management objective many regions around the world. One way for cities conserve enhance drought-resistant vegetation cover. This revegetation practice can take place on types of land, including road-side verges (also known as nature strips or boulevards), which, Western Australia, are publicly owned but managed privately by residents adjoining properties. As preferences alternative verge groundcovers not well understood, designing solutions that help achieve goals and satisfy communities a challenge. We survey community members Perth, find peoples' landscape design largely bimodal, be classified under two dominant groups people: those who prefer native vegetation, which requires little irrigation, watered grass. Neighbourhood norms prevail their rankings, where individuals whose neighbours have planted water-conserving gardens also more likely ecological designs. Increasing extent feature plants high-profile public areas may further increase acceptance low water-use groundcovers, assist driving practices towards having designs verges, beyond.

Open lawns are important for cooling urban areas and providing space recreation activities. However, research on the benefits of is lacking, additional provided to by irrigation have not been explored. It fill this gap optimize layout design develop proper lawn maintenance schedules cope with more severe heat in future. This study explored mechanisms regulators open empirically quantified lawn-induced Changzhou, China. In study, differences thermal environments hard surfaces were measured, changes environmental parameters during after irrigation. Lawn area had a significantly lower mean PET (-1.16°C, p < 0.001). The effect was pronounced at night (-1.99°C, 0.001) than day (-0.33°C, 0.05), as long-wave radiation main source night. During first 37 minutes afternoon irrigation, irrigated unirrigated (-1.74°C, 0.001), suggests that may provide lawns.
