💻 I took several completely independent datasets and "pitted" them against each other. One of the results is shown in this chart: the more "concrete" (roads, buildings, parking lots) my machine learning model identified in a community, the higher the surface temperature recorded by the thermal sensor.
🔥 The result: Data from different sources confirm one another. The difference in surface temperature between "green" and "concrete" residential areas averages 8–10°C throughout the summer. On certain days, this gap is likely even wider.
📉 This chart shows only established residential communities. If industrial zones were included, the trend would be even more dramatic. While modeling errors certainly exist, the overall physical pattern is undeniable.

Diana E. Frimpong et al. (2022) assessed the relationship between land use land cover #LULC change & air quality trends over the past 30 years in East Baton Rouge, Louisiana using #Landsat5 & #Landsat8 imagery, #Sentinel5p & air quality index from the EPA. #LoLManuscriptMonday https://bit.ly/Frimpong_2022
Cheers to Diana’s co-authors and affiliated organizations for this manuscript, and thank you especially to our lead Matilda Anokye for leading this Manuscript Monday feature! #EOChat #GISChat
