Conclusions Atlanta is a urban heat island
The urban heat island phenomenon is best seen through comparison of minimum temperature data Could be due to atmospheric mixing created by solar surface heating during daytime Increasing urban vegetation could help reduce heat island Lowering albedo Increasing evapotranspiration
