Pielke, who said one issue ignored in the paper is that
land surface temperature measurements over time show bigger warming trends than measurements from higher up in a part of the atmosphere called the lower troposphere, and that still needs more explanation.

land surface temperature [data] to define the... most heat - exposed neighborhoods I believe is completely justified, since this is a relative measure of the most heat - impacted neighborhoods,» he wrote in an e-mail.
For their paper, published in Applied Geography, researchers at the Earth Institute at Columbia University and Battelle Memorial Institute studied air
temperature data from weather stations,
land surface temperatures measured by satellites and socioeconomic data.
