Hot ‘Lanta in May

Hot Lanta

On May 11-12, 1997, NASA used a specially outfitted Lear Jet to collect thermal data on metropolitan Atlanta, Georgia. Nicknamed “Hot-Lanta” by some of its residents, the city saw daytime air temperatures of only about 26.7 degrees Celsius (80 degrees Fahrenheit) on those days, but some of its surface temperatures soared to 47.8 degrees Celsius (118 degrees Fahrenheit). In this image, blue shows cool temperatures and red shows warm temperatures. Pockets of especially hot temperatures appear in white.

50 degrees Celsius = 120 degrees Fahrenheit = flat roof temperature. The red zone looks to be about 30C = 86F, but these are surface temperatures. The 1997 survey recorded air temperatures of 80 F – exactly the average high temp for May for Atlanta. Cool.

In other words, it’s a peachy image of normal surface temperatures for the city.
