Spatiotemporal Variability of Heat Storage in Major U.S. Cities—A Satellite-Based Analysis by Joshua Hrisko, Prathap Ramamurthy, David Melecio-Vázquez, Jorge E. Gonzalez

“…The subsequent model was used to predict the total heat stored across 10 major urban areas across the contiguous United States for August 2019. The analysis presents a positive correlation between population density and heat storage, where higher density cities such as New York and Chicago have a higher capacity to store heat when compared to lower density cities such as Houston or Dallas. …”
